Sounds like you are dead in the water . So far I have been lucky. I do see that one of mine is bent a little. But just in case I purchased a spare one with a Basic Atom, so that I could when necessary figure out what the differences were when running the Pro vs the atom.
I take it you are completly dead or you can also just try to jumper from either grnd or +5 to the io pin to see if the interrupt is triggered.
Good Luck
