I get this error over and over when I start the battle.net app, but can so far log in and play normally, but every time I leave game the error is there. I’ve already uninstalled and reinstalled the battle.net app, any other suggestions?
edit: Found it. I allowed World of Warcraft launcher, World of Warcraft, Battle.net Launcher and Battle.net through my security, but had missed the Battle.net Update Agent, agent.exe. Added this to the whitelist and updated without a problem, so if anyone is having a similar problem, give a quick look to your security.
