The following are likely causes for this exception.
- If the current game uses the XNA Framework Redistributable. This file does not include Games for Windows – LIVE functionality.
- If another Games for Windows – LIVE title is running already.
Games for Windows - LIVE is not available to finished games. This functionality is not included in the redistributable version of the XNA Framework. A game that attempts to use these components without XNA Game Studio installed will result in a GamerServicesNotAvailableException.
