Guilty Gear XX AC Plus CMP Files

I'm pretty sure these are some kind of background as I've never really played it. I've
tried the Kirby Return to Dream Land CMP script, (works well with it and Fortune Street. Just edit the command to say CMPRES format.), yet it will say 'ERROR. CAN'T EXTRACT THIS FILE'. All it does is output like 2 bin files that are like 6kb. Please help!
