Hi there, il got a problem with cardbook. Here is my setup: Cardbook 33.4 Thunderbird 52.9.1 32bits (need this version, couse of extensions Inverse SOGO connector) Thats happening: I updatet to Thunderbird 60.x this got lost my SOGO connector, so i downgradet to 52.9.1 to get it back, since then my cardbook keeps losing the adressbooks il create after a restart of it. So i got into the \AppData\Roaming\Thunderbird\Profiles\k7roctw3.default and deletet all the cardbook relatet files, also in the prefs.js But... it doesnt helped... il start thunderbird, create the adressbooks, il close it, il open it, all is gone.... Doenst know how to solve it... pls help. What u need?
