Changed to Glass skin, now XBMC Crashes upon load

Help!

I wanted to check out the Glass skin so I downloaded the Passion Repro and installed it. From System > Appearance I changed to Glass skin, worked fine. As soon as I backed out to the Home screen, XBMC froze and I was forced to kill from the task manager. Now whenever I load XBMC it freezes instantly. Is there any way to change skins from outside XBMC? Can anyone help?

Thanks!
