I have been having the same issue and I’m under deadline. If someone could please write out the steps to fix it would be a lifesaver.
MACHINE
OSX v10.93
2.3 GHz Intel Core i7
16GB 1600 MHz DDR3
PROGRAM
Davinci Resolve 10.1
Same issues as mentioned above. Re-installing does not help. In fact, I can’t create a new user at all. When I ‘create’ the new user, nothing happens. And somehow the database was disconnected, my user status lost. I have all the footage, I just need to access the program again (RT from FCPx) so I can begin color correction and connect to raw footage for export.
