Hi, welcome to the org.

When you say reloading, you mean reinstalling, right ?
From what I know, the Geforce 8600 is known to have problems with Shogun, there's two ways around it: change your graphic card, or switch to "Software device", or hardware, I don't remember in the graphic options of the game.

Were you asked to enter the serials on the first install ?

Anyway, you should post a thread in there or ask a mod (Mithandir I think) to move your post into the Apothecary.
