WotLK Unable to connect

[SuperSwede]

Hi.

I can't logon on to warframe servers for some reason.
It says: ''Unable to connect''.
Yes I use the account name which i created on the site not the email.
I have checked the realmlist files, and they're correct.
Tried to create new ones. Didn't work.
Tried redownloading the client. Didn't work.
Tried connecting to another wow private server. No issue at all.
Does anyone have a fix for this?

UPDATE: Downloaded the old download on the site . Not with the updated models. And it worked right away.
