I hope running as administrator solved it, one last thing: I have been getting issues while running the game. I get error #134 after I logout of my computer. This seems to happen for no obvious reason, so I will be investigating for further informational purposes.
It may be possible that your game file is corrupt, or your computer is unable to handle WoW and the initial setup.
I get the error all the time, I solve it when I log back in and run the game after deleting the cache. I have a feeling Curse Client may be in the mix here. Give me a list of any modifications you have for the game, and any addons you are using. Let me know if you have curse, and your OS as well. I will be looking into the error further as I had stated above.
These issues started at a more recent patch, and after I had manually downloaded and extracted an addon. This is not likely going to cause the issue, but I need more info from you folks about the error codes, explain any changes that were made between when the game worked, and when you are getting the code.
