Need some help.....

My problem is that it wont display the given image, can anyone tell me
what thing ive done wrong or missed. I changed something and I cant
remember what..... its going to be one thing that needs to be changed
back :S

It only displays a small white box inside a JFrame that is the colour
I want it to be.

theCAS_Engine works perfectly. Like I said I changed something last
night and forgot to run it to check it worked and now it doesnt
work :S

Thanks,
Peter
