Today, my 8700c's calendar just decided to stop working and I don't know what to do. I don't do anything advanced with my calendar (such as syncing w/ my pc) but I do use it daily. Can anyone please help me?? The error message reads exactly: "Uncaught exception: Unpaired Graphics push in class net.rim.device.apps.internal.calendar.viewer.WeekF ield" and the only option is to press "OK" and thats it, then it just returns to the home screen. What can I do to fix this and is there a way to do it w/o losing my data??

Do a backup, wipe the device and reinstall the OS.
