I think they still are trying to make windows 8 compatible because some games arent meant to be played on it yet @duhvietboy.
They did this along time ago.
OT : This happened for another member but on Win7 he didn't solve it so far , try uninstalling Pandoo media booster.

make sure you contain the requirements for playing crossfire
Check z8games!
It's probably something about the z8ganes requirments that your computer isn't meeting. Check it out, and if that's not the case, then send CrossFire a support ticket.
Did u try re-downloading?
Uninstall Pando Media Booster, it is un needed and may fix your problem
also with Windows 8 you HAVE to run it as "Administrator"
