Hi,
I had the same issue and deleting the older translation fixed the problem.
The only problem since then is that many of the translations are gone.
The Events latest is now completely in english which is not a big problem but the "View Full Calender" is now visible in the frontend which was "Ganzen Kalender anzeigen".
Is that a problem of the language file? As far as I could remember this text could be specified in the module parameters but I cannot find it anymore.
