I was prompted to upgrade to PC version 4.4.0; after this upgrade, the PC database schema is not compatible anymore with my iPhone database and sync is impossible.
Helpdesk asked if I was a beta tester. I’m not and never was. Helpdesk advised and mailed a link to download new version.Same errors again.
Finally succeeded to install PC version 4.3.2 and sync works.
So basically, I can use Codebook and sync, but I can’t upgrade anymore…
