I am having some difficulty with Lightburn, in that I have some work I am attempting to send to the laser. It frames perfectly fine, however if I select the whole piece, nothing happens, and I have to hit stop (sometimes reset). If I select a section at a time, or each piece individually, it works fine. There are no error messages, it just doesn’t do anything. Can I send in the file, and what kind of debugging info do you need? I have a 28x20 Red/Gray, with KT332N controller. I am running a MacBook Pro, and I do have the lightburn bridge.
I can not help with your LightBurn bridge, I do not have any, but if you want I can check your lbrn2 file, whether it will run normally with my controller (also a KT332N)

How many files are hosted on your controller? Have you ever deleted any?
Go to Window > File List to make sure it’s shown, click the ‘File List’ tab, then click ‘Refresh’. If you have a lot of files stored in the controller, they can get weird.
I have pretty much emptied my controller memory. As I was going through each section of the file last night, I found a few flaws, and using edit-nodes, I was able to clean them up, and right now, I am re-running the job, surprisingly, it seems fine now. There were just a few places where a spike existed that couldn’t be seen until I zoomed way in, but it is working perfectly now. Sorry for the disturbance 
You do not have to be sorry, as long as you have found a solution, everyone is happy. You have asked nicely, got a few answers and finally found the solution yourself. And not to forget, others with similar problems will possibly be able to use it to solve their problems, this is what the forum should (also) be used for. 
Indeed! If this question helps others, all the better
