I hate movie maker first of all. But I can't afford to get a better program. Actually I just don't want to spend the money.

WMM will no longer let me import ANY time of video to edit. It says it's the wrong video format, when I've been using the same format for over a year.

Any idea what's wrong?

1. You can do a system restore to back when it worked (this is a pain if you install new things frequently so I don't recommend this)

2. Download the video codecs you don't have to load the videos you want.

I had this prob about 3 weeks ago. It's a pain so I just used my other comp.
