BUZ problem...sigh

If i record a movie in premiere 4.2 all goes well untill i want to playback this freshly captured file. it does not playback, basically... windows tells me :

"MCI error - blah,blah, too many drivers loaded, blah."

I tried deleting all the activemovie files because the new IE for Win98 might cause problems and i reinstalled the old activemovie from the buz cd but that didn't work.

can anyone help? i'm really thinking about re-installing windows.
