CF not running on Win32?

Dear Z8games,

Please help me with this problem. I recently reinstalled CrossFire because my computer needed to be fixed. After i reinstalled, i logged on normally then when i exit to check the forums i go back on and there this message appears. : crossfire.exe has been changed : then when i check it in its folder i try to click on it and it says : crossfire.exe cant be played on Win32 : or something like that. I reinstall again and its okay but when i log out and go on again the same thing happens all over again. Please help me.

Sincerely,
RexlTory
