Hi and thanks for replying. I'm using Avast anti-virus and every time I tried to run the exec. file I got a warning and the file was quarantined as it supposedly contains 'FileRepMalware'.
I managed to figure out how to exclude the file so I can now enjoy your game. It's very nice and I hope it scratches an itch I've had for years, you see I used to play a game called Fire which was based on a very old DOS game I believe (it might have been called Olaf or something). I don't seem to be able to find it any more.
