Because I need a way to access my *.gp3 files, and kguitar doesn't work (it crashes when I open any *.gp3 file), I tried to run gp4 with wine.
Everything works ok, I can see my *.gp3 files (well, except for the part with the notes, where a large B appears instead of the normal dot, but as long as the tab is ok, I can live with that).
The problem is when I try to play the file. It gives me this error, in french, although the program is in english:

Violation d'acces a l'adresse 05AB615 dans le module 'gp4.exe'. Lecture de l'addresse 00000011.

What does this meen? I have to mention the fact that when it starts, it plays that song that is usually played, so it can access the sound...
Should I post the output in the console when I run the program? It doesn't say much.

Any ideas what I should do? Or at least a suggestion of what tab editor I can use that works and will play my file? Any info and tips are welcomed.
