Won't let me put serial number into product

I got a mclaren gt3 wheel end of June this year and everytime I enter (the correct) number it doesn't accept it? The robot self help is of no good. How can I seek help to correct this. Thanks
I know it's the wrong place but I don't see another way

Fixed now. Thank you very very much.
I can't see how to delete thread. Getting old is no fun
I am having the same issue with mine.
I think it's because it's a different product ID to what it actually is on the store, so some help would be great!
Cheers!
