exe error?

Hi.
I working on my client exe. I wounder if there is a program that can show me error?
It's pretty hard to edit the exe and the only error you get, is that client closes.

So is there a debugger or anyting like that I can use?

Ollydbg is your debugger :D

i see...

So how do I get it to show errors ?
right now, I save exe, and try it
