You also need to update the program after you install it, because they never compiled it for the new OS.

Sometimes when chessmaster crashes, it will leave the engine running in the background. This leftover engine can use all the CPU time and make things run slowly. Close chessmaster, then look for a program called "king350.exe" or "theking.exe" or something like that in your process list in the windows task manager. If you see one running in the background, use "end process" to kill it.

LMAO!!!!!!!!!!  I heard about that happening to some guy, and now I know it was you, lol.

I have it, and it runs slow toward the endgame for some reason. And I fall within the computer specs by a longshot. I guess it's just how it is.

It's probably stalling for time waiting to see if you are going to blunder in the end!!!!!!!!!!!
