Media Player and Activemovie window

Archived from groups: microsoft.public.windowsxp.general (More info?)

I recently installed and then removed the program Pinnacle Studio 9 from my
computer, and now things have tanked:

None of my media players work, even Windows Media Player or any other one.
They attempt to play a file and then immediately crash (WMP give me the
message AppName: wmplayer.exe AppVer: 10.0.0.3646 ModName: ivivideo.ax
ModVer: 4.0.11.369 Offset: 0004ae90)

Several other programs now also don't work. As soon as they start, the
Activemovie window (which is black and unresponsive) pops up several times
and won't let me go back to my program. Even when I close the window it pops
up again as soon as I restore my program window.

To make matters worse, the computer does not let me load any restore point
from before the install.

Is there any way to restore/fix this problem? Please let me know if you can
help me out.
