update issues with official warmane MoP client

I downloaded the Warmane MoP client from this website (not the minimal one) and I am playing on Frostwolf. I chose Pandarien and there are multiple bugs with interaction of some things like vehicles. On the red question mark in-game where you see FPS and such it says that download: 0% and 0mbps dl speed.

Here is what it looks like, is this what is causing the bugs in the game? How do I get it to actually update?

btw sorry if this isnt the appropriate forum

it is ok, it always shows 0%.

If you still thing something is bugged then feel free to download full client via torrent ( it is 28 gb)
