Hi,
Time/Date/Region set is OK. I checked them.
And yes, I checked the online/offline row in the Origin menu earlier as you wrote. I got "go offline" text there.
After reboot and start Origin, the windows attached below appear (pic 1 - sorry the first pic-text is hungarian - it is an ask for permission to make changes, pic 2, pic 3).
After password the Origin automatically starts the SimCity "finalizing" so I do not make anything. In the next letter i'll send you pictures about that.
I dont find "repair" option anywhere.
