I am the creator of a NING 2.0 Network. I back up our site using Adobe AIR, the NING instructions on how this works can be found here: https://www.ning.com/help/install-the-ning-network-archiver-on-your-computer/. ;
Today, I tried to sign into the service and it rejected my credentials as being incorrect. I know this cannot be the case, as I am using those same credentails to log into my site and this site. The issue appears to be on NING's side. I've opened support ticket 1887537 to track this. I'm starting this thread to learn if other creators of 2.0 networks are unable to use that service.
