I purchased Sylenth from LennarDigital, and after installing it and entering the manufacturer's serial number, it prompts me to restart. However, I can't work with it. Every time I open Sylenth again in Cubase 13 Elements, I get the same message: I can't work with it.
I have restarted Cubase and the PC in every way possible.

Please uninstall Sylenth1, then search all your VST folders (including subfolders) for any leftover files named Sylenth1 and delete everything.Kenny Meller wrote: Fri Jan 02, 2026 9:42 am I purchased Sylenth from LennarDigital, and after installing it and entering the manufacturer's serial number, it prompts me to restart.

Also manually delete the following folders (if they exist) on your drive (this is essential):
C:\Program Files\Common Files\LennarDigital\
C:\Program Files\Common Files\VST3\LennarDigital\
C:\Program Files\VSTPlugins\LennarDigital\ (or {whatever VST2 folder you're using}\LennarDigital)
After that, re-install the latest full version of Sylenth1 and activate as usual.
That'll fix the problem!
