Has anyone tried to use Chessmaster 11 with the electronic board made by DGT? There are guidelines on the internet regarding the use of a third party application called "Gamekeeper" which suggests that Chessmaster 10000 is compatible with the DGT board. I have followed the instructions for "Gamekeeper" with my new copy of Chessmaster Grandmaster Edition but I cannot get it to work with a DGT board. Any suggestions?

Yes, people do use Chessmaster 10th Edition with the DGT Board via GameKeeper... see this thread. As Chessmaster Grandmaster Edition is very similar to Chessmaster 10th Edition, I don't see why it wouldn't work as well (although I'm not positive).

According to the GameKeeper Help File, you need to make sure that notation is set to algebraic (I can't imagine why one would use anything else), and features such as Pause, Resume, Takeback, and Replay aren't supported.
