Hi, So my first guess is that it looks like you are trying to run it on win2k or xp. And I've only tested it on Win7/Win10. I don't know for sure which OS you are running it on, and I am only guessing based on the window manager theme. If you send me an e-mail roderick.mackenzie at nottingham dot ac dot uk, and tell me some more detail about the computer you are running it on I will be able to help you more. Have a nice evening!
