Okay, so last week, I was making a video on WMM and it was working fine. But I soon scrapped the idea of making the video, cause I got bored of it quickly.

Days passed, and I realized Windows Update was not on. So, I downloaded the SP3 (Service Pack 3) on my PC.

Days passed, today rolls around, I realize I can help my boredom out by making a video. Well, upon opening WMM, it says it encountered an error. I searched on Google and everywhere, but nothing helped.

I do however believe it is indeed SP3 that is messing it up. Here's the file that will be included in the error report:

C:\DOCUME~1\HP_Owner\LOCALS~1\Temp\150f_appcompat.txt

Anything else you need, just say and I will post them on Additional Details. I already tried to re-install WMM, download other WMM, but nothing works.
