I have tried to restore me iPod that is disabled due to typing in the wrong password too many times. iTunes keeps giving me a box saying that it can't connect because I need to type in the passcode on the iPod (which I can't) what do I do now?

I have followed the steps provided by apple to restore an iPod touch. It is disabled due to having the wrong password entered too many times. When I get part way through the restore process on my computer it pops up a box saying that it can't restore until I enter the passcode into the iPod. I have tried this same process over 5 times now and keep gutting the same results. It is my kids iPod and he has only had it since September. Someone please help me before I throw the thing through the window and my kid strangles me!!! Thanks!
