any help

* sorry if my English is bad

I guess the decompiler did not do a good job. You will have to spend more time with the source to create a good version.
Can you contact the author of the program and get a clean copy of the source from him?

i would like to add, i think what he means with clean is readability, naming conventions
its hard to understand most of the codes, its hard to tell which is class which are variables, its even hard to determine what those methods are for.
