Apparently you need to do a clean install. I downloaded 0483 and chose to do an upgrade and keep my settings. Although this works the security zone is set to medium after install which is not really keeping my settings. Importing my settings from a backup locked me from the internet again.

I did the clean install restored my settings from a backup and it appears to be working with settings back on High and max. So I guess you should do the clean install but back up your setting before you uninstall.
