Secular

Oo, and i'm running XP.

When i put the first cd in the menu pops up, I click install and nothing happens. In task manager it has the setup there but its inactive, just sitting there, taunting me. Copied the cd to my computer and tried it from there and the same thing happened. I assumed my CD was just screwed so i d/led a version from pirate bay then tried to install it and it did the same damn thing. I've played this game ON this computer before so I'm flat stumped. Any help would be appreciated
