MoP client error on startup

Hello!

I've downloaded the MoP client through torrent (not the minimal one) for windows, and on startup (wow.exe) it's thinking for about a minute then throws me an error: https://cdn.discordapp.com/attachmen...78/unknown.png

Any ideas? I'd love to play some good ol' Molten/Warmane again

EDIT

I was curious and bored so I downloaded the minimal client too. After a short installation window the game started up as supposed. I could even log in to Frostmane.

Follow these steps:
1) Restart your PC
2) close your Torrent client and move your WoW folder away from your Torrent's download destination
3) now right click on WoW folder> Properties> remove "read-only"

I have not tried (due to minimal working for me) but a friend of mine said it was working for him.

Thank you
