sometimes I got an error in GP5 so I couldn't play the file. (But I was able to see the notes etc.)
This doesn't really happen anymore, now I have to deal with another error.
When I open up the song (it's just that one song) it says this:

"Violation d'accés á l'adresse 0065FAFB dans le module 'GP5.exe. Lecture de l'adresse 000000.14"

and there's just an empty GP5.
Till now there was no helpfull awnser. Saving and restarting didn't work etc...
Somebody can help me?
I just downloaded another version of the song. Of course it works now but I still would like to see this one.
