Every time I attempt to start the Launcher Optimization, I always get the same error. I start the process and I get to about either 1% or 6% and then experience my problem. My problem says "Can not access necessary files. Please check your internet connection." I am connected to the internet, have reset reset my computer, restarted my internet, removed all .lock and .mpq files from my data folder and tried again. I have deleted my battle.net folder and tried again. Currently, I am in the process of reinstalling WoW entirely. Once it is installed, I will try the Optimization again, but, assuming it doesn't work, does anyone have any advice for me or is anyone experiencing this same problem?
