Every time I am in world lately, the lag worsens as I am in a region; than after about 10 - 15 minutes, the program freezes, and closes completely. This is frustrating, and unenjoyable. Please offer help. ADDENDUM: Dell Laptop using Windows VISTA. Pentium(R) Dual-Core CPU T4200 @ 2.00 GHz, Memory (RAM) = 2.00 GB, 32-bit Operation System, Graphics = Mobile Intel(R) 4 Series Express Chpset Family. Also, how do I check my memory for failing sectors?
