Messed up registration (on company end)=no support

I just registered a new RAX1200 that I received but I messed up the registration..... zipping thru the dropdowns I selected 2009 instead of 2019. grrr......

I uploaded proof of purchase, but there isn't a way to contact support.

I messaged a moderator of these forums, but I haven't heard back....

So what do I need to do?

Thanks.
