Is your add-on manager digitally signed. I have been having problems and have had a corrupted download so I'm checking to make sure. I downloaded KJFK with no problem -- the file was signed by you guys. But the add-on manager comes back with a warning and an unkown publisher.
I'm sorry, not yet. We are in the process of digitally sign all setup right now, the stand-alone Addon Manager wasn't. However, the installer itself has a built-in checksum verification so, if the file was corrupted in the download, you would surely get an error during the setup.
