[quote name='gizmogc']I did that...nothing has changed. It still only lists 'Windows Classics' and 'Windos XP'[/quote]How about if you just click the '.msstyles' file in the original folder it downloaded to. Does that change it? It does for me, wish I knew the technicalities behind it, but I'm just learning myself.
Just looking at mine, I've still only got those two themes you listed, plus two Aero ones, that I don't use. The one I'm currently using is in the 'Themes' folder, but doesn't show up in the 'Display Properties>Appearance' window. Yet, it's still up. I'd bet Tiphireth has the answers.
