When I try and drag any file from BaseHead or my Desktop to my DAW (Especially Pro Tools) it doesn’t work?

You need to shut your UAC off to fix this.  It’s a known bug reported by Avid and that is their official fix for it! hahaha

Also, if you run a DAW like Cubase ‘As Administrator’ you will get the same problem until you turn the UAC OFF.

TBH….The UAC is quite worthless so shut that worthless thing off…8)
