I just started playing Sunday night when I got it and when I go into Lakeside Country, the game will load the files and get to 100% then just kick me out. Any help please? Also, why is my game so laggy?
If so, check this thread for information on how to get around the problem.
The game was made with firewall friendly in mind, but there are a few odd cases sometimes.
Your system should run it with little lag, but on average it eats up at least 180 of your memory. Running processes in the background could deny it the memory needed to finish loading a map.
