Cataclysm Install Errors

Technical Support

About 4 weeks ago i installed Cataclysm & patch it to 5.0.4 before the MoP release without any problem.I play the game 1 week for check to new talent system then uninstall it.
Now i decided to play MoP and try to install Cataclysm again but it start to give 2 errors.

1. one is, when i put the disc and try to install, its stuck at "Connecting to server..." then gives a error : "Unable to connect.Please check your connection and firewall settings.".
I closed Windows Firewall & my EsetNod32 AV5 but it still gives same error.But when i re-click to my DVD again sometimes install is starting...Lets say i press to "Install" 10 times, its give 6 times error or 4 times install starting.

2. one is, when installing the game its always stuck at %5 like 5-10 minutes then gives these four errors in same time.

You should only install the game using the Mists of Pandaria discs or by downloading from Have you since uninstalled the game, or are you trying to create a second installation?
