I know that Movie Maker hates MPEGs, but today I stupidly tried to import an MPEG movie in order to convert it to WMV (I didn’t have STOIK on my laptop at the time, but have since downloaded it). As expected, WMM (Windows Movie Maker) immediately crashed and had to shut down. Fine, that’s what I figured would happen. But now EVERY time I start the program, I instantly get the “Windows Movie Maker has encountered a problem and needs to close. We are sorry for the inconvenience.” I can ignore that popup for a moment and even mess around in the program, but after about a minute it freezes up. Anyway, is there a way for me to fix this? System Restore doesn’t work (in that it won’t restore to any of the System Restore points).
It would be helpful if I could reinstall WMM, but that does not seem reasonably possible. Yes, for those of you who don’t know, you *cannot* reinstall/uninstall WMM through “Add or Remove Programs.” I downloaded an installer for WWM 2.0, but I’m afraid to delete all traces of the current version and try reinstalling… I could also try reinstalling Windows Service Pack 2, but I don’t know what repurcussions there might be, or if it would solve the problem. I have read one way to reinstall WMM, but it requires a Windows XP or SP2 installation CD, and I don’t have either, since Windows XP came preloaded on my computer and the backup is in a harddrive partition.
I’ve Googled my question to death Everyone who asks seems not to get an effective answer, except for those who happen to have the Windows XP installation CD.

I’ve tried downloading the file from Windows Update, but it is not even listed as a download option for me. I downloaded the installer from Download.com, and ran the installation, but it did not change anything.
