Konpik,

I am having the same issue with two different machines and am also using Cloud.  Uninstalled and reinstalled the app, played with firewall on/off, and added Tabbles to rules list settings and nothing seems to work.  I too have used Tabbles for many years and have a rather large database built.  Sorry, I have no solutions, but please keep us updated if you find a fix and I will do the same.
