Okay for sometime now, whenever I go into the Ubi server browser to connect directly to an IP, I will get a stop error. This is becoming increasingly infuriating because it's making it impossible to play this game with my friends. No matter what I am constantly getting stop errors while trying to play. I don't understand why all of a sudden it's be happening. I don't think It's the RAM because I can close all other programs and it'll still give me a stop error. I have no idea whats going on.

My specs are:
AMD XP1900+
GF3 Ti200
512MB DDRPC2100
