Yeah... I'm having the same problem, except this is my first ever account and it's rejecting me.. or not allowing me to even log in.
also.. with 3 different places to input a password i don't know which is used for what and how.
the profile viewer is rather hard to navigate, I've tried to find a way to change my profile picture, for a while, but found no such luck.
also.. some of the stuff on this site doesn't show up properly.. i sometimes have to refresh the page several times before it shows anything..
I am using chrome, although i don't know if maybe the site is just rejecting chrome or what.. but ehh.. not really something i'm too worried about..
