I am running Windows 8 and when I start the game the only screen resolution I am offered is 640 x 480. Playing at this resolution is impossible as the on-screen text is unreadable, even on resetting the monitor resolution to 640 x 480. I've tried various compatibility settings, but all without succe...

I'm only offered 640 x 480 which makes the game unplayable as the text is unreadable. Any suggestions?
