null reference exception meansyou are most likely trying to access a member or method of a null object.

Maybe you can use try - catch blocks in your code and log the error. there is not enough information here to debug your code.

try
{
}
catch(Exception ex)
{
log(ex.toString());//write a logging message or even just pop up a message box.
this should give you the line number where the exception was thrown and then you can more easily find your null object.
}

Step through the program and find the exact line that throws the null reference exception.
Then come back and post the bits of related code, noting which line caused the error. We might be able to pick out more from seeing that.
