Loading fails??

So, here is my story. My cousin saw me playing CF and he said cool game then he want to download it and play with me. Besides he download it he want me to cop the "Crossfire setup 1088" to USB and paste it in his PC. Everything was fine from installing, opening games, joining rooms, no errors... But when he click Join game, the screen turn to black and you can do anything, u just can see your mouse. So he Alt+Tab out side and he saw alot pop-up messages like:
MISSION_BUTE_FILE Loading Failed
CLIENTBASICPLAYERINFO_BUTE_FILE Loading Failed
ITEM_BUTE_FILE Loading Failed
TP_BUTE_FILE Loading Failed
MODELNODE_BUTE_FILE Loading Failed
BOTNAME_BUTE_FILE Loading Failed
WEAPON_BUTE_FILE Loading Failed
MATCH_ITEM_INFO_BUTE_FILE Loading Failed
DISTRIBUTIONBOX_BUTE_FILE Loading Failed
GP_BUTE_FILE Loading Failed
And then i told him to uninstall CF and download it directly to his PC. But we can't solve the problem, the same thing happened.
Any suggestions for my cousin's problem? I would appreciate.
EDIT: He has windows 7-64 bit.
