I have Ulead Media Studio pro 6.0 install, but when I try to insert a audio file (MP3,AVI,MPEG...) I received an error : "Could not open file... Contain no audio data."

And sometime I received an error: Could not locate the file c:\my Music\sarah.mp3"

Could you help me, because I tried to re-install Ulead Media Pro 6.0, but the problem stay there.

Thank you very much for your help.
