I played Sierra Games back in the 80's. You would think that after 20 frickin' years in the business they would have this crap down. Tonight when I tried to play Vengeance online, I got the ever popular, "The Product Key you are attempting to use is already in use." Their online forums don't list Vengeance as a product. The online form to e-mail customer support automatically forwards you to the forums. I called them... they are closed. I found an e-mail address... we'll see how long it takes them to fix this. This sucks.
