Thanks! It worked

My steam account has an underscore ( _ ) in it, but you can't use underscores in your username for the forums. When I run iw4m.exe, I get this: [NP] Initializing RPC [NP] Sending RPC message with ID 1. [NP] Sending async RPC message with ID 1. [NP] Sending RPC message with ID 0. Performing Steam authentication... Error during initialization: Your current Steam account does not own Call of Duty: Modern Warfare 2. Please purchase the game or try another Steam account. I do own the original game, and I have 182 hours on it. Is it because my forum username is different to my Steam account username?
