I just started the monthly payment plan in order to buy Sylenth1. When I pasted my license code into the plugin it told me to restart it, but every time I reopen the plugin it asks for my license code again and again without ever unlocking.
(I'm using FL21 on a laptop with windows 10.)
Any help would be appreciated!
Having trouble activating Sylenth1

Hi,
To fix that, uninstall Sylenth1, then search all your VST folders (including subfolders) for any leftover files named Sylenth1 and delete everything.
Also manually delete the following folders (if they exist) on your drive:
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.
