After upgrading to a floating license, having a second window of Lightburn open is giving me issues. For over a year now, I have had no issues cutting or saving changes to files with multiple Lightburn windows open. Recently, Lightburn will not save changes or get the laser to cut once I open a second window. I open a file and cut it on the laser, then I need to cut it again but I want to add something from another file so I open a different file in a different window and copy and paste part of it into the original file (both open at the same time in different windows). Lightburn will still frame the new cut file with the pasted in parts, but it will not cut it and it will not save those changes. Once again, this only started after upgrading to a floating license. Any ideas?
I suggest you send an email to support@lightburnsoftware.com. You’ll likely need direct support for this and the LB folks might not see this here immediately.
Thanks @berainlb, I have seen this and looking into it further. This is not something I have seen reported previously, so checking with the rest of the team. Will report back shortly… 
I emailed lightburn support and they told me it has nothing to do with the floating license and told me to revert to the trial version. I never had a trial version but they don’t seem to understand that. I have tried a complete uninstall and reinstall and that didn’t help either.
I should also add that this is happening on two different computers. Both running windows 10 home.
Correct. Multiple instances will take multiple floating seats because of the way our key server works, but that should be it. The software does not restrict the way it works based on license model type.
What version of LightBurn and how are you connecting to the laser?
Looking into our systems, I see one of the support team members offered the following to help in understanding why we are asking you to try moving to a trial license to test your results and see if doing so resolves the issue you are observing.
To clarify, on the reason we are asking you to deactivate is that when you do it will kick you back to the Trial. The Trial will not be a floating license type so it will be easy to see if that does resolved the behavior you are seeing.
If you are willing to test this, here is the process…
To deactivate:
- Run LightBurn
- Go to Help > License Management
- Click “Deactivate”
- Re-run LightBurn and proceed with the trial. If your trial is expired, copy and paste the trial key here and we can extend it for you. (Do not post your Float key here in public
)
Version 1.0.06
Thank you. And how are you connected to the laser?
Where are you trying to save these files, local, networked or cloud storage?
I am connected via ethernet. I tried to deactivate and run again, but since I put the license key in with the command prompt, it is just reopening with the floating license.
For this test, don’t do that. We are asking you to run the trial. Do not pass any command-line arguments when starting the deactivated version of LightBurn. This should present you with the trial version so we can check the save results with that version.
I didn’t put it in again. It is still in there from when I first switched to the floating license. I don’t know how to remove it.
Ah, so sorry for not including this information. You will need to delete the lightburn.ldata file from the LightBurn program folder. If the software finds that, it auto-licenses itself on startup. You can move it to some temporary directory for this trial testing.
I reverted to a trial version and this problem went away. It is working as it did before the switch to the floating license.
Are you running any anti-virus software on your computer, or any kind of domain restrictions (like a corporate network)?
I can’t think of a single reason that a floating license would affect whether LightBurn can save files. I’m wondering if perhaps your anti-virus software interpreted the license server check as somehow malicious, and tried to prevent LightBurn from writing files as a result. It’s a stretch.
Can you put yourself back into ‘Floating License’ mode, and if you’re having the same issue, go to Help > Generate Support Data and paste that here (or email it to support, along with a link to this thread). I’d like to have a look and see if anything strange is showing up there.
