WotLK Cant Login or Update

[Crillin]

When i try to log in with my account name it appears unable to connet please try again later.
And when i try to log in with my email it enter, starts to update, asks me to restart to apply the update and says that the update failed

what should i do?

you need to log in by using warmane account name, not email address.

about the "unable to connect" issue, wait a few minute.
Have you downloaded the client from Warmne ?

Yeah, i downloaded it from the warmane site
