Runtime Error on Ubuntu (Natty)

I'm running Ubuntu (Natty Narwhal). I installed Wine and MP3tag v2.49. The first time I tried to use MP3tag, it worked fine. But every time after that, when I start the program, I get a message that says "I/O error (win32 #998)". Then, when I click File, I get a message that says:
Runtime Error
File: .\sfile.cpp
Line: 608
Code: 00000000
And then MP3tag closes, and I get the I/O error message again. Anyone wanna help please?
