I have this same problem with every song on one of the first albums I ripped. With version 1 software I got a sort of "tweep" sound at the end of each track. They play OK on winamp and music match. In version 2 the player plays the whole song and then with 2-3 seconds left on the counter it says "Invalid File Format". It looks like whatever ripper I used at the time (I was experimenting) seems to have tried to add a 2 second silence to the end of the track and messed it up. Anyway, I just re-ripped the tracks and all is well now.
