I was so taken by the demo that I bought two copies plus one for a friend yesterday so that I could play against my son, and the game works fine on one of my XP machines, but on the other I get this:

1st screen

Critical Error

Access Violation


2nd screen

SDL_app: mahemig.exe - Application Error

The instruction at "0x5ed2aed8" referenced memory at "0x00000564".  The memory could

not be "read".  Click on OK to terminate the program.

----

Any ideas what this is so I can get around it?
