Guitar Pro 6 Soundbanks

[Bitter Jane]

Hey there. I have just recently migrated to Ubuntu (Natty) from Windows and I'm having a bit of a trouble with the installation of Guitar Pro. To begin with, I was able to install it, since it was a .tar file, without using Wine. When I had to install the soundbanks, however, I got stuck. I can see there's an executable named GPBankInstaller in the installation folder, but it won't open. Trying to open my soundbanks.gpbank file through it didn't work either and using Wine is not an option (I guess), since the installation of Guitar Pro didn't involve it.
So, is there any easy way I can install the soundbanks (I'm a newbie)?
Thanks in advance.

Fixed. I installed Guitar Pro "the Windows way" (using Wine). It didn't open, but the soundbanks did install. I managed to replace the Soundbanks folder within my Ubuntu installation and voilà, it works!
