When I log in the game and all of the data is checked for any patches in the game, it stops dead at this;
File Process Patching:...nd_Dialouge-WorldData.wad
I tried closing the launcher then reopening it, but it said that Wizard101 was already running on my computer and I might need to restart the computer to play Wizard101.
Normally I connect to the game using FiOS, however now I am using a high-speed broadband connection. I am using the same computer that I did with the FiOS connection.
The first step is to find that file you're stuck on (usually in C:\Program Files\KingsIsle Entertainment\Wizard101\Data\GameData) and delete the file that's giving you all the trouble.
Run Wizard101 again, and you will download the most recent version of that file.
