A bit of a stupid question

So. I've changed the Realmlist, I followed what the Downloads page said to do by "enter your Warmane account name" yet I always get an "Unable to Connect". So I went to check my firewall and all that gunk but nothing there was wrong yet I still get the same result, "Unable to Connect" even though my internet is quite stable. What the heck am I doing wrong?

Make sure you use the account name you use to login to warmane and not your email id.

make sure your password isn't more than 16 characters. the website will accept it, game client won't.
