I reactivated my subscription hoping to play Rift again, but right now it seems like I wasted my money :-/
When I launch the game from the launcher, there's no interface. I'm on the character select screen (from what I can remember), but there's nothing to see. It's just the background being rendered. No character, no interface with buttons to click, nada.

Other games render just fine, seems to be isolated to Rift.
