Guitar Freaks 2nd Mix Ver 1.01 (GQ883 VER. JAD) [system: System 573 BIOS - folder: gtrfrk2m - size: 512kb]
integrity check failed: 929jbb02.chd [reason: can't access file]

I haven't sen this error before... I thought it might be due to firewall or other programs accessing the file, but I think I've ruled that out.

If anyone can shed some light i'd really aappreciate it!

thanks
