Hmmm. I'm guessing since you're running win7 64bit that ram is not a problem..I can't check that file right now, but I'm guessing "small village" means it's not a very big city.

Try making sure that the .sgs file is in the same directory as the program and see if that helps.

Sometimes I get a crash on the windows version with a really big city, but then the linux version works fine. Maybe it needs recompiling with a better compiler...

I should really start quoting people to make it clear who I'm talking to. I don't normally participate in such active threads...
