Game Problems

Hi i setup the lines but i changed the game to full screen 1920 by 1080 and it comes up with am error amd does not work properly and ive not figured out how to get it working again

You're going to have to be a little more specific please

What does the error message say?

If you're using a recent build from http://openbve-project.net , then in the bottom left of the main menu, there is a link which says 'Report Problem'
Post the logs from here, and it it's a game problem, I can take a look.

Windows issues are more tricky, but until we know what the error actually says, there's not a lot we can do.
