Hey,
I bought the V-Collection 3 a few weeks ago and wanted to register it now. But when I choose Register a new product in my Account page the V-Collection 3 can't be found in the product list. I can see V-Collection & V-Collection 2 in the list though.
Im using Safari 7.1 on 10.9.5. I created a support ticket as well but thought i might throw it out here on the forum in case this has happened to someone else.
