If you have problems downloading, installing, running, or playing a game, you can get technical support by e-mailing Pumpkin Games Support at support@pumpkin-games.net
Always observe the system requirements for each game. Ensuring you have all the pre requisites will fix 99% of all problems.
*DirectX note: Don't assume you already have it even if other games run - there are optional parts which may not be on your computer. Run the web installer and it will check and add missing parts. Don't assume that becuase you have the latest SDK installed that it will work either as SDKs do not install the optional files from previous SDKs. We can not stress this point enough - its the most common reason for XNA apps failing and we often see people who ignore this step becuase they think they know better.
Please note - If you are experienceing problems running Doppelganger on Windows Vista via the Start Menu, please try either (i) elevating account permissions or (ii) launching the executable directly from Explorer.
