Razer Deathstalker V2 Pro Incorrect Serial Number

I’ve located the serial number under my keyboard, manually put in the serial number in several times by now. I keep getting the same error saying I might have typed it in incorrectly, even though I’ve checked it multiple times and also tried to replace the 0s with Os. ☹️
Please help me, I want to register my product. If any of the Razer Staff is looking at this, please talk to me and register it for me. I will provide whatever evidence you require.
