I keep getting a blue barrier that prevents my movement into locations. This happens at random, and requires a restart of the game to resolve. From information I've gathered online, this barrier indicates I am still downloading content from the server, however when I check the launcher it indicates content is 100% downloaded. Also, I am playing 4 other accounts at the same time (Multiboxing) from the same hard disk location, and the other accounts are not exhibiting the same behavior at the same time. They do the same thing at random for no clear-cut reason.

When this happens, I am forced to restart the game. (for that window, the others continue working fine) It should also be noted that when this happens, the game refuses to acknowledge my logout/exit request, so I am forced to ctrl-alt-del end process to close it.

What gives?

Have not seen that kind of thing myself.

You could try to launch each account solo, and go through the Launcher rather than wow.exe and see if they're all patched up.

What software are you boxing with?
What are your computer specs?
