Answer 1

Start commenting out lines of code and entire classes/methods from your code until you get it working (Or start by commenting out everything). Then slowly start introducing lines of code and method calls etc. Until it breaks. This should give you an idea of any particular code/class or reference that is causing the problem. This is admittedly a tedious method, but at the same time, fairly mechanical and within an hour or so you should have a fairly good idea of culprit.
