When I load My Cross Fire After the HGW the screen flashes black ...

When i load cross fire, after the patch the Xtrap and HGW, the screen flashes black but after that the crossfire log into game window doesnt come up anymore, i reinstalled it, redownloaded it, repatched it and disabled firewall aswell but it all doesnt work. is this a cross fire problem? or i need to check my computer or files? cuz my other games work fine.
