I've had this game a while, but recently I had to reformat my comp due to a virus (I think, not sure preciseley what it was).  anyway, after reinstalling the OS, I updated it to Vista SP1 and then installed Sins.  updated that to v1.16, and suddenly the program has epilepsy.  I mean that any images, including menu buttons, menu framework (visual), and player "avatars" are continually cycling through all related images.  if I hover my mouse over one button, all seem to take on that button's "image", without the text. 

in-game, this also happens with planets, menus, etc.  obviously, this doesn't let me play.  any ideas on how to fix this?

p.s. by "epilepsy" I mean that it looks like what you'd expect it to look like if the comp was having a seizure continually(not freezing, just changing pics extremely fast)
