Yes I have.
I've tried getting to work a few times but each time exploer fails to load so I have to run system restore from the installation disc.
I had the same issue myself with the Aero Diamond theme. Other people don't seem to have the problem which is why I decided to keep it on the list. Though it seems to happen when messing with the color personalization options (and after messing with those options you can't access them again, some weird error will occur). I also had to do a system restore to just before I patched my uxtheme.dll file. So you're not the only person with this problem xD
