I bought it yesterday, and when I ran it for the first time, the auto-hunting stops and crashes 1–3 seconds after I press “Start.”
There’s nothing in the log file, and I’ve already re-downloaded the client and reinstalled all the required programs it asked for.
I’m using the MoP 5.4.8 version.
It seems a few other people had similar issues, but I couldn’t find any solutions since no one posted how they fixed it.
Is there any known fix for this?

Hello,

What do you call "auto-hunting"?
Is it the game that crashes? Do you download the game client from the server's website? (or is it an original game client)
