File damaged?

Hi, guys. I'm trying to convert the ASF files of NBA in normal WAV or MP3 files. I've downloaded the SNDView 0.42, but when I try to play the created WAV files, appears a windows that says the "File is damaged". What I can do?

Thank you very much!

I don't think you can do much. EA's .asf files have a special code that won't let you read them
