No worries. Let me know what the team says about the logs.
It's just Windows 7 Home Premium, and it updates automatically. Is that what you're after? I'm running the same version of N360 (21.3.0.12).
The D drive is 241Gb, the backup folder is currently 184Gb, which is about 40Gb bigger than it was the other day.
I'm really confused now; I checked the restore option before, and it was 21.4Gb, but now it's telling me that there are 'No backup sets found.' And the backup drive in My Computer is there, but there are no files in it...
