So I re downloaded the game after a long hiatus, I literally had no problems what so ever running this game before. I have an alienware mx17 specs as follows:

4.00 GB Dual-Channel DDR3 @ 533MHz
Generic PnP Monitor (1440x900@60Hz)
256MB GeForce 9400 (Dell) VERSION 280.26
Intel Mobile Core 2 Quad Q9000 @ 2.00GHz
Penryn 45nm Technology

When I re downloaded the game it informed me that I may have graphical problems because my graphics drivers were not up to date or something like that. I went ahead and looked for updates for my graphics card and installed the few that I could find. After that I found that when running the game, it's kind of choppy and not as fluid as it was when I played it months ago. What's going on? :(
