Map Error, NEED HELP!

Can anyone help me resolve this issue

ERROR #134 (0x85100086) Fatal Condition
Program D:GamesWorld of Warcraft 3.3.5aWow.exe

Failed to read File

1. Download the client again( https://www.warmane.com/download ).
2. After it's done downloading, run a hash check/recheck on the torrent task to make sure it's 100% downloaded and no packages were lost.
3. Copy your WTF and Interface folders from current client to the new redownloaded one.

I have the exact same thing...

I have done everything that @shhnedo has said.
Downloaded a brand new client
I'm not getting the Northrend map error anymore
I am getting the Isle of Conquest error instead

Makes no sense what so ever, I've never had anything like this happen before

Apply Large Address Aware program to wow.exe.
