my droid calender won't open anymore. I had previously gotten it up and running after having to sync it and all that stuff and it had been working fine. now all of a sudden when I press on the calender app or the widget, it opens up for half a second and immediately closes. I recently installed advanced task killer and im not sure if i killed the calender or not. I must have or something because its not working. is there a way I can un-kill it? and advice if that is not the case would be greatly appreciated too, thanks!
