Game won't run, going crazy.

Hey guys, been lurking for awhile but only just made an account.

Maybe it’s cause it’s 1am here and I should go to bed but I’ve been working on my first java game and it was working fine up until now.

It runs as expected in eclipse but when I export it as a runnable .jar it will start the game (load the first option box) then close, i found it to be an error loading one of the image files but what I am confused about is it was working perfectly earlier and still loads the images fine when run in eclipse yet I haven’t changed any code.

If someone could take a look at the code or try and export as a .jar and let me know if you can get it working
