Hi I got a similar problem with the same program I tried to get around to see some documentation but unfortunately I was able to find out nothing. In my case using gcompris 2 and mandrake 9.1 the program starts but after that I cannot run the single games.
If I'll be able to find some solution I'll post a message here, please the same make you in case you can solve the problem.
Best regards
