I have imported sound from my computer into movie maker. It shows up with a yellow warning sign and claims the file is either corrupt or unrecognised. However I know they are compatible with Windows Movie Maker as I looked it up (I tried .wav and .wma). Sound from video files work, but my imported sound does not work at all. Also according to my computer the software I have for this, AMD Radeon, is all up to date.

I know you guys are amazing so any help would be greatly appreciated.

Thanks!
