Dewaters

I didn't know whether to post this in the general troubleshooting or here but I have the game on Steam so I guess here. I'm having trouble playing OA and Combined Operations. Whenever I run these with Teamspeak 3 the game gets random crashes after about 5 or ten minutes. It exits to windows and a box pops up saying windows is trying to find a solution to this problem(which obviously it never does). As far as I can tell its not happening with the original Arma 2, only OA and CO. Also when I installed OA I had that CD key problem which I fixed, just in case that's relevant. My laptop: win 7, 64 bit, Home Intel quad core i7 @ 1.73GHz 4GB Ram Nvidia GEFORCE GT425M On steam: newest patch of the game I've looked around for this problem but can't seem to find it. Sorry if I have done loads of things wrong here this is probably my first post on a forum ever. I also found this if its a help C:\Users\Stephen\AppData\Local\Temp\WERAB6C.tmp.WERInternalMetadata.xml C:\Users\Stephen\AppData\Local\Temp\WERC9A7.tmp.appcompat.txt C:\Users\Stephen\AppData\Local\Temp\WERD1C3.tmp.mdmp
