So i downloaded this server with old character models a few months back, played it for a few hours and stopped, and today i came back to log in, and when i log in, it says its downloading something, then says i need to restart wow to install the patch, i press okay, it throws me back to the log in screen and says there was an eror, that i have to re install or contact support. Is there a way for me to fix it without having to download the whole thing again because it will take me hours...
