I'll start with a technique.
Every so often in any program, put:
#ifdef DEBUG
(output that says 'we got to this point')
(possibly output that lists what values variables have)
#endif
Then in the start of your program:
#define DEBUG 1
or
#define DEBUG 0
depending on whether you're debugging or not. :)
This will tell you which part of the code is failing, rather than you
having to guess.

Find out. :)
