random errors

i keep getting random errors during game. it ether pops up as "disconnet from server" and the game still goes on but i cant do anything but press ok and game crashes. or it pops up a bunch of numbers starting with 2 then some more. i have looked around the fourms and the so called "fix" for the disconnet from server didn't help and the random error fourm/patch barly did much. i can barly play a game without getting one of these error codes. i don't have any external programs that could effect it. i used to have tune up utilities but i have disabled it because i find that when it's on it gives me the error code more often. my antivirus is trend micro internet security. i have put all files possible on the trend micro as do not block/give access(i have to do this ether way or the internet security will not let me start up crossfire). and just in case i run crossfire as administor. i cannot take a screen shot because the game wont allow and whenever i use the print screen botten the crossfire game screen will turn black
