Graal Reborn login trouble

I am currently having a problem logging into the graal reborn game thing I downloaded it says my name or password is incorrect any solutions?

You gotta go into your UserCP on the forum. On the left had navigation bar near the bottom will be a link where you can change your in game password. I think if you logout of the forums and then log back in you will see some instructions on how to do this in a yellow box.

It just requires that you close your browser window, at least for Firefox.
