predcon: At first it was just that clicking the "Registered Users" link on the Launcher dropped me on the main TW2 page, and not on anything resembling a page where I might setup a profile. Now the Launcher won't even connect, leaving the DLC and Registered Users links greyed out. Are CDPR's servers maxed out or something?
The whole thing about profiles doesn't work yet. It's connected with the log-in functionality of the website, which probably will go back online together with the forums.
As for the connectivity problems: I'm having the same issues for a few hours now, others do not. But it's no real trouble as the game and all DLC (that is already installed) remain usable.
