My subscription recently expired and I've had to go back to my fallback version (2018.2) and I seem to have lost some of the settings that I had previously set up. In particular, the code arrangement and copyright settings that I had spent quite a while setting up are no longer available.
I've tried syncing the settings with my online account and it claims that has succeeded, but I still can't see the missing settings. I've tried importing from a previous install (all later versions that 2018.2 - although one is close: 2018.3) and the importer claims these aren't valid config folders or installs.
My projects also seem to have all lost their settings with the src folders etc. no longer specified.
