Well, I was away for the morning and the boys have provided you some great insight. Between them there is a wealth of brewing knowledge there.
Wow, that photo shows a lot of un-crushed corns. I stopped counting at 15! Considering the small amount you have there that percentage is terrible indeed. Maybe show your home brew store that photo when you explain your issue. It must have slipped through when they milled it. We all make mistakes and don't be too hard on them.
Still it's a good learning experience and it would still be good for you to test your equipment and review your processes as you have said you will. At least you'll know for any future issues. As Lyrebird said, you have lots of unmodified starch there and there is also likely to be mix of issues (ie a process issue like mixing or dough balls going on too).
Great learning curve this hobby isn't it.
EDIT - grammar and general poor English used!
