Rendering wont work...

[Last Phantom]

So I export it as a movie with the settings
Avi Uncompressed Audio tick.
Res 1280 720 720p
Sequence Seconds.

After it renders, the file can't be played in Windows Media Player. It gets "Windows Media Player encountered a problem while playing the file." Nor can I get it to work in Windows like Movie Player. Do I have to render it as another file type?

Also when I start SFM I get
sfm.exe - System Error
The program can't start because tier0-s.dll is missing from your computer. Try reinstalling the program to fix this problem.

Yet it still starts... Could this error be causing the renders to mess up?

To get rid of the Tier0 error, close your Steam Client and restart it after it finishes updating.

As for the render, it could be for any number of reasons. Once you get SFM back on-line, re-render the movie. Also, try to render it as a mp4 files.

The problem is that Windows Media Player only uses a few codecs but not all of them, so that's why you can't play the file in WMP. Use another multimedia player as VLC[www.videolan.org], that will work.
