I'm getting this error now and can not save my Hotbar loadouts. "One or more of your client settings files, which include your Hotbar settings, failed to save." I've read old posts about this but nothing seems to help. I'm using Norton 360 for Gamers as my anti-virus and firewall. I also use Norton Utilities. Please assist!

Ditto here and it happens randomly. Not sure why it i occurring.
