Contacts and Calendars 1.02 after upgrading

After upgrading to readynas 6.4.0 i also updated "contacts and calendars"(c&c) from 1.0.1 to 1.0.2. After update c&c was broken. It didnt sync with devices anymore and it replaced my sqlite-database with all data with a new (empty) one. Luckily i had a backup cronjob running and was able to restore my data. I had to switch back the app from using mysql to sqlite, too and (not sure about this) recreated the passwords for the users.

Regards.
