So you want someone else to fix your program, so that you can charge money for it? Sounds kind of sketchy, don't you think?
Seriously, with all of the optimizations that the compiler does, it is VERY difficult to read the machine code and figure out what the problem is.
I would try getting the latest service pack for visual studio, and then recompile. If you still get the error, then it's time to walk through the debugger. If you are serious about selling your software, this is something you should really learn to do.
