Can not join the game

registering for an account that won't log me in.

I made an account registered with this game in order to to download the game

when the client was finally downloaded it asked for me to log in

naturally i typed in the same information to login the website
but tells me its invalid

what do I do so i can finally play?

Make sure you are signed in to the "Forums"
On this page click at the top where it says "Account"
Then click where it says "Game accounts"
If you don"t see the one you made listed click the "Blue" "Link an existing account"
Enter the info, then click the box "I have read and agree" then click the "Link Account" button.
