Can't loging

I used last key over 1 week, but now i cant login.
[17:52:43:068] Authentication failed!
[17:53:45:099] Logging in...
[17:53:45:279] Invalid product key!
But i uses the old key that i bought here. All 3 sessions is free.

 

I logged in just fine, mate, so I know that the service is online.
Are you certain you're typing in your login key correctly?

I just copy it from buddycenter. Also my bot works fine at morning, but after relog it i can't login

 

If you were disconnected or started a new wow client, have you, also, closed HB and started it anew?
I get a similar error if I haven't closed the pre-existing HB window and restarted it.

I'm disconnected but i kill all sessions at buddy auth portal.

 

Also how can i link my shop account to forum account?

 

You cant.

btw. looking at your Join Date, when did you first buy hb?
