Welcome to the forum. I am sorry to see that you joined under these circumstances. My suggestion would be to contact the seller on ebay. He should have given you the code when you purchased it. This is not the first time I have heard of this. When purchasing a MyGig from anyone, always ask first if the code is available. If he can't give it to you, there has to be a reason. Your only alternative would be to take it to the dealer and see if they can help you.
