Hi
I believe you that it isn't a photoshop scam, but a real serial "1" would be written like this:
#000000000001 and not just a simle 1.
I have one of the erliest A1000-keyboards and it is written:
Made in Malaysia
#00000000129
(version be/ch)
I think you have been cheated, but for that small amount you spent.
