License not seeing DSP controller

Good evening, initially I downloaded the trial version for my new DSP based machine, with which I have been working and testing the software, I activated my purchase license on the desktop computer, until everything is ok, when I restart the version of purchase I discovered that it detected my other laser based on gcode “snapmaker”, so I activated it too, but it no longer detected the main laser machine based on Ruida, so I entered it manually, working perfectly, today the version of the Laptop that I have at side of the expired machine, without remembering that I had it in a trial version, and knowing that I have up to 2 terminals, put your key number to activate it, my surprise was that when I went to detect my machine it told me that I did not have the DSP version active, which I’ve been working with and why in the end I decided to buy the license, I don’t understand now why it won’t let me activate the license if it has been working.

In the same way I cannot send files to the machine because either it tells me that I do not have DSP activated or it simply does nothing, after reading this forum I will try tomorrow to install the versions indicated, if it were something else I would appreciate the comment. Thank you.

You purchased a GCode license key, not a DSP license key. I have provided instructions over email for you to upgrade the key.

Well, you will forgive me for this indication, when you put a test software, being tested, and seeing that they work and convinced that it is the right one, and when a license is acquired, tell me that I have to upgrade to another why not They recognize my controller, when I have been using it for all that month of testing and at no time have I received notification of having to request an extension to be able to run with the Ruida controller (dsp), I do not understand why it is not indicated from the beginning. I am a domestic user, I do not have this out of necessity, just a hobby, and for wanting to contribute because according to what you indicate on your page, you are a small company and have expenses, I chose the option that I could afford, to be well with you , and now I find that I have to pay to be able to control my machine, it is honestly not the answer I expected based on your web information, which from the beginning certainly worked.
