Right? In other words there shouldn’t be a restriction on any software I download from My VSL? And I don’t’ need to re-register. Right now I can open Vienna Instruments Pro standalone and get the same error message. In all my years of using VSL, I’ve never encountered anything like this, so thank you and let me know your thoughts. I've been usign Vienna Instruments Special Edition for about 8 years. Now all of a sudden I'm having problems with Vienna Instruments Pro coexisting wiht Vienna Instruments. You're not using the same key from 8 years ago are you?Īlthough I think Paul is on the right track with his 'software problem' diagnosis.
