I have contacted steam about the in valid cd key error, did everything that support said still doesn't work. Contacted jowood no response, this sucks when you buy a game and it does not work. All I need is a valid cd key! Steam should have warnings on games that are known to have issues, I basically threw away 15.00. Is there a solution to this problem? I run on vista, done the admin thing still no go! This will be the last download i do from steam. If want to buy a game I will get a hard copy instead, extremely furstrated!
