Yes, Mac OSX El Cap.
What about the rest of the info the link I posted asked for?
With the information I have available, I suggest uninstalling AE, running the Adobe CC Cleaner, and reinstalling everything. That should let you get updated too.
Although, you could start by trying to import that project into a brand new one.
Damn, apologies. I thought that was a auto-placed SEO link or something. I am the worst person ( I mean that. Well, not as bad as Stalin.)
Adobe CC would not connect to server yesterday. Continually failed. Was not an issue with internet, nor password.
Connected now and update fixed the issue.
I apologize for wasting your time. I am, however, glad to know I didn't break something.
No problem. If you need anything else, just post a new thread!
