I get stuck at "Checking for updates..." and it lasts for about 2-3 minutes before crashing and saying it failed to run the program "Agent". I open my process manager and I have 3-5 copies of Agent running. I end the processes and start over and the same thing happens.
I have tried uninstalling all Blizzard products (2 copies of WoW, MoP beta, D3, SC2) and restarting many times and still nothing. Any help?
