Database corrupted after updating to sync3.6

After yesterday's updating to sync 3.6 the database is corrupted, and it is not possible to import from a backup sqlite-file - there is an JavaScript-fault (German "Kein Übersetzer wurde für die ausgewählte Datei gefunden" means in English "No translator found für the chosen file".)
It's a pity because I had collected some 500 titles in Zotero. What to do?
