Halion Sonic Error Message

Hi. I’m using Halion Sonic SE2 with Cubase Pro. I had a free trial of the newer Halion VST and once it expired I then uninstalled it seperately from Cubase.

After doing this, I now get a message saying “No Layer Edit Page Found. Please make sure that the required VST sound instrument set is correctly installed”
I googled the issue and some people seem to solve it by reinstalling Halion Sonic SE2. I tried this and the message still pops up.

I mainly need this fixed because it won’t let me access the pitch wheel in order to tune the VST instruments and I don’t know if there’s another way to do this with Halion.

Has anyone else had this issue?
