Incorrect Password

Okay, I'm not sure which part I'm doing wrong here...

I came to the site, I registered, I then went to my email and activated it, after that I downloaded the game and opened the launcher as it said and it just has a start button.

I clicked start and then put in my username and password and it said it was incorrect.

Tried multiple times until the game closed on me.

I went to the site and then tried to login on the main page and not the forum and it said "Account not found".
So I'm thinking maybe I did something wrong so I went and tried to reregister and it said "Username or Email already used".
Went back to my email to make sure I used the right name and yeah... I used the right name.

I went to the account management on the forum (seeing as I can't even login on the main site) and went to change my password. I changed it just fine.
Went back to the launcher and started the game up.

I tried my new password and the same issue:

Note: Yes I tried typing my username in all lowercase and just the 1st letter uppercased. Nothing worked.

I can't log into the main site. Only on the forum.
The main site also said the username or email was already signed up when I tried registering.

So the site is saying I can't register because I already registered, but it's also saying I can't login because my info is wrong or the account doesn't exist.
