Well I tried to install an ollder version (1.2.2 - Yes I know its not compatible with P.R 1.3... ) and it messed up my OS. It didnt boot up and i had to flash it..

Ok I wrote some birthdays into contacts later and MeeBirthdays and my calender are notices that and is showing the birthdays.

The problem is that MeeBirthdays doesn't schow me the birthdays of all other contacts that were constructed automatic...
How can I solve THIS problem?

Edit: Seems to be a known behavior
