I was using WMP 10 on my work laptop. When I tried to play the file, WMP gave me an error code complaining about the ID3 tags. When I actually tried to pull up properties information on the file, I couldn't see any text through Windows. It might not even be a problem with WMP itself, but just some other Windows update or font that they didn't install here. I don't have the latest patches (as we're restricted from actually installing software updates ourselves), so maybe that's why it happened.
It worked fine on WMP after I used a program to reset the tag info.
I also just synched my the original file to my mp3 player, and it works fine. It's probably just something weird with my Windows setup here.
Just thought I'd mention it in case anyone else had any difficulty.
