Okay, I admit I was stupid, but in my defense cloud profile menu is very confusing.
It offers to create or change the password, and since I don have a VorpX account already, I tried to change it. It redirects me to the page to change my account password (the one used at forums).
But what I HAD to do, is to create a new, separate, cloud profile right inside the UI. Then it lets me log in. So those are separate profiles, huh?
