Vista - Windows Movie Maker stops working

I bring up the program and within 15 seconds the sreen goes white and says the program not working.

Then it scans itself and says its shutting down and will notify me of any fixes.

Happens everytime.Please help.

right click my computer > manage > computer management > event viewer

Look for Windows Movie Maker and post the contents of the log please.

Here's one error. This was in the details section :
MOVIEMK.exe6.0.6000.163864549b5b6QuickTimeAudioSupport.qtx7.6.3.048ba2f99c00000050017b3027c401c94754da01051c

This is a window that pops up sometimes when WMM shuts down"

assert failed
Executable MOVIEMK.exe Pid 3600. Module
QuickTimeSource.dll, 3 objects left active!
At line 317 of .\dllentry.cpp
Continue(Cancel to debug)

De-bugging only re-starts the program then it the same ol same ol happens.

I think its messed up because I imported a quicktime clip by accident and its there in the library with other clips. I tried deleting it from the library in the short time I have the program on.It seems to delete but the delete never takes as the QT clip is still there when I bring it up again.

My son has a different profile than me (same computer)and his WMM works with no problem.
Thanks!
