Trouble signing in - stuck at "connected"

[MayfireD2L]

Hello,

I joined around 1 year ago on April 5, and played for about 1 month, then took a break. Today I felt like playing WoW again, and realized I had this account.
After multiple attempts to sign in (with correct credentials obviously), I am stuck at the "Connected" state, right after "Success".
Any leads? I really don't feel like starting over, I miss my lvl 80 panda monk.

*EDIT: Problem solved, was using 5.4.2 old version, figured 5.4.8 is the newest.
