well, i had that same problem a while ago, buti don't remember how did i solve it, sorry.
What you can do, is have a recordstore were you can store each process step by step so you can check in which part the problem is being generated, cuz this one won't tell much. You can later have a TextBox on which you can write what was stored. Its what i do when deploying application to devices, i don't have the output on a device, so i store the things on a RS and later check them, like a LOG
