Im locked out of my ipod and i just got a new computur and wont sync?

I lost my ipod (in the couch) for like a year. My stepmother found the one i lost and locked me out, im not really sure what the password is anymore, i cant try because it doesnt work. And i got a new laptop recently and moved all my music and my accounted and got ride of the old laptop and right now, when i try and unlock my ipod on itunes it would let me and it says the same things, "Itunes can not connect to the ipod ' Abbie' because it is locked with a passcode. You must enter the passcode on the ipod before you use connect to itunes." and then a try again button and then cancel button... when i click the try again it just pops up again! Im not sure that to do.
