My phone, Calendar and Contacts will not open

[jstatham]

I loaded Mighty Rom release on 1/4. Everything was working fine until this morning. I now click on the phone to open the dialer and the screen flashes and does nothing and goes back to the home screen. When I click on contacts or calendar it shows the black htc screen and then goes back to the homee screen. Has anyone else had this issue or do you know how to fix it? If I go thought all applications and click the phone contact or schedular non will work. Any help will be greatly appericated. I am thinking of reflashing tomorrow with the latest might rom but would like to know how to fix it.
