Registering Hbird

Just bored since I have been on hold with hummibird for 32 minutes now. They must have alot of issues or just not many people. I am trying to register my 777c2 online but it keeps telling me the serial number is invalid. I have called and spoken with someone before and was told it would be fixed so the product could be registered. It did not work after waiting a week. I then e-mailed them the information and was told the same thing. This was last Thursday and I still can't register the unit. I have double checked to make sure the serial number is correct. Could I have maybe registered the product before under a different name? I would like to update this unit. Well someone just give me a different serial number to register so I could gte updates (very nice lady). I guess I could have gotten updates some other way. I was going to delete since my problem was resolved but I had already typed all of this.
