Here is my help:
The entire line of output up until the actual error means absolutely nothing to me or anyone else except you; it is means anything at all, then you need to get into your debugger and start stepping thorugh your code until you hit the error and see what is actually happening, then if you are stuck, write a question stating what the problem is and where it occurs in your code. You chould give some of the variable states in the same scope during the iteration inwhich the error occures, but unless you are willing to do this, I doubt anyone is going to do your debugging for you--paticulary since this is not even your own code.
