I had trouble making an account for a long time. Tried everything. Finally was able to create an account today.
Heres how:
Allow all scripts, all pop-ups, adds etc. Basically open the floodgates on all pages through the account creation.
If all scripts are allowed, but some pop-ups are blocked, it will just say “unknown error occured” when you try to make an account.
Hope this helps. I know a lot of people are having problems signing up.
