thanks.. yes it was just the cockos ones were gone, the JS stuff was still there.
It's possible while I was trying some rescan stuff , clear cache etc.., to add Addictive Drums, I messed something up, because the error happened after that. I was pressing all kinds of rescan's and Alt P, per some poster comments from 2008...to get
Addictive Drums (but that never worked either). It makes sense probably I erased the path or something.
I just deleted all the Addictive Drum stuff, and copy&pasted
the Reaper Folder from my Cdrive to the folder in the GdriveUSBHD, and it works again.
software to me is like asking someone who doesnt play a guitar, to play a guitar...lol
at least I learned something about the Alt P and "adding" a VST...well, havent done it successfully yet, but Im getting there.
