have you tried downloading and installing Vintyri 2.1 ? Don't ( Problem fixed.)
I downloaded it last July as I wanted to reinstall everything from his site, as I had a few missing symbols.
I backed up the mnu files as suggested.
I did everything exactly. It said it had to uninstall 2.0 first, was that okay ? I clicked yes, then it asked was I sure ? I clicked okay.
It not only uninstalled CSUAC_2, it took out my Annuals folders, Bitmaps, and the only thing that loads now is CC3+. None of the add-ons load either. Error is 'Cannot find LOADCD' etc.
So I will be reinstalling everything I have.
I suggest that you don't install the Vintyri 2.1 without backing up your entire CC3+ data folder first.
