Same problem for me (and it seems some others, going by the forums). Tried disabling all extensions, tried different browsers (without extensions), tried restarting computer, tried logging in and out a bunch of times. One time when I was logging out, strangely, it acted as if I was a brand new account - giving me the terms of service, resetting my username, showing no campaigns on my My Games tab, etc. That cleared away as soon as I logged out and in again. I would assume there is a problem on roll20's end :)
