My buddy and I have been trying to team up so I can help him level up (he's a 36 Capt. and I'm a 48 RA) but the last couple of days, every time either of us sends a team invite to the other, he crashes to desktop. We had one time where we stayed teamed for about 20 minutes, but eventually he got dumped. He can play fine solo with both of us on teamspeak, but the second we try to team up, POOF!
I'm having a similar problem, I'm able to join a team but after about 10 minutes no more than 20 my entire system locks up forcing me to do a hard restart. I can play the game fine as long as I'm not part of a team, for hours and hours and i don't have this issue with any thing else, but once I join a team it's a matter of minutes until my computer seizes.
