Any program that has this:

while(1) {
[download]

will keep on running forever unless you do something about it.

Maybe you want to put a stop condition into that block?

i edited it but now the program doesnt execute.. it just gets called and stops..

Keep editing, you still have nonsense syntax, eq doesn't work like that

This isn't very helpful. What did you change when you edited the code? Have you tried going back to basic debugging to find out what's going wrong? See Debugging and Optimization from tutorials.
