If you try the game before you put it on your CD, make a copy of it first!!!
Reason: You've got an unregistered version, and the first time you run the game, it sets a serial number that will be there forever. Then if someone does register the game, all of them will send me the same serial number...
NOTE: Could you please put the game in the "Shareware City/games" folder instead of in the Reader´s Contributions folder?
