I cant open my calendar, every time I open it it just closes and says Application Closed, Application :Calendar, Reason Code: Agenda Model, Reason Number:0 any ideas? Im tempted to format my phone but I'll go with your suggestions first, Tnx.
:-?

maybe try a reboot?

tried that already,
anywyz i fixed the problem myself, i think its some sort of a bug...
I just opened a backup of my calendar in my MMC and then I was able to open the my new calendar... weird huh? anywyz, its all good now, good thing I had a backup though..
