Tower Defence Game - Need help to continue

[Codeless]

Ok so I've been following this tutorial for building a tower defence game, after an hour I try to run it and get an error. I re-watched the tutorial twice and spend two hours comparing code and I can not figure it out.

Please, this would be such an interesting project, help me resolve this so I can continue.

here is my full code

this is the image I used created in gimp

kblpe.png at Free Image Hosting

and this is my output

Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException

ad infinitum

please help me out guys, I don't know what this error means it doesnt give me any method or point of reference I'm familier with, what is the eventqueue and why wont it behave?

100,700,999 ziggle points for the solution

sorry I forgot the code! moving files to shared folders in order to communicate with your guest OS is tiresome

You'll want to post more of that error message, and you'll want to indicate which line(s) cause errors.

[Codeless]

thats all that comes up in the console, it doesn't give me a line number - I can't seem to extract more information out of it either which is part of the problem, can you give me some advice on how I can debug this?

Sorry honestly this didn't show up until after I enabled line numbers

what does this mean, there are a few number references here

also the exception in thread to the bottom seems to be repeated

[Codeless]

that issue was solved by changing the -1 to 0's in mission1.td

however I have another problem

1 0 0 0 0 0 0 0 1 1 0 1 <----- only this line seems to work

here is the output

you can see the line that is working corresponds to the output

whats the issue here?
