Error while changing to google calendar - no function now

Hi,

i deleted the system calendar app via titaniumbackup and install google calendar
something went wrong

I don't have a running CalendarProvider.apk and calendarsync
Google Cal is running but i cannot interact
account google shows no calendar sync
I need a hint and the files please and where to store them and how

worst case is to reinstall ROM - but where can i get it for PLK-01
thanks in advance
