Hi, guys.
I recently purchased the K13 Ulti UPD KS.
I felt good because I bought it at a reasonable price.
And, thanks to the recent NKS collaboration of my hardware
I registered KS 15 in my account.
So I tried to activate K13, but they said the base product is different.
I can't get KS13 itself at the moment, so how can I register K13 Ulti?
