Yes...I know it was a beta and all the cautions that come with it so spare the "I told ya so's....." LOL! Anyway, after installin teh WMP 9 beta 2 weeks ago, it worked great for a week, but NOW it won't play ANY type of format....keeps giving me "unknown format" errors for EVERYTHING....MPG, AVI, ASF and even MP3 !! Anyway....anyone have a link for the 9 beta, lost mine. or at least some way of uninstalling it....let me guess...I CAN'T uninstall it, right ?!?!
