I've done just about everything I can manage myself from the official help page on this topic-- except I'm on an iMac with no disk drive so I can't use the disk to simply reinstall.
I restored all of my files from a time machine backup and the other adobe products (bridge, etc) work. Photoshop is a no go with the notirous "Licensing stopped working"
I've gone top to bottom on that official help page and whenever it has me looking for a file, it's not there- no flexnet, nothing. How can I fix this?
