Same problem here.
I believe you should get an asus code after you register your product on your asus account.
But I don't see any info or message for an asus code afterwards. :/
(i have a red *) on my profile "Country/Region"
and i have a red * in the details of my registered product with the message :
* For your own rights and benefits, please update the correct information of your product within 5 days from the date you registered.
DO you have the same problem or message?
Have you found a solution?
Gretting, thnx for reply
