I've had the cloud issue as well for the last 4 days. My main av was a cloud to me and everyone else, I've done all of the recommended steps to clear it up. I finally got my av to appear to me after using the character test several times over the last 2 days. I have a folder set up with a copy of the needed parts to rebuild him and replacing outfit works except for the gray that won't go away. To my alt and everyone else he's still a cloud. I've restarted my router and modem twice, Pinged a few west coast sites I use for speed tests and all seems good. I finally uninstalled all SL clients including removing registry entries. Reinstalled both FS and the official viewer and no change. My alt is fine and has no issues.
