I can see Sitala in the synth rack but I can't open it. If I replace the vst with another instance of Sitala it opens but it's empty.
There are no error messages.
There are no audio files related to Sitala in the audio folders, this is the problem. They just vanished. The only thing left is the MIDI information.
However, now that I think about it, before making the beat I reactivated Cakewalk on the official site. Now it doesn't ask to be updated anymore, is it possible that Cakewalk updated automatically when I restarted the PC, messing up my project?
