Not sure what's going on, Whenever I click on the apps the icon bounces once then stops without opening. Happens with the App Store, Messages, FaceTime, Reminders. Mail opens and loads just fine but I can't read any of the messages. When I click on one nothing is displayed but a no message selected message. I don't have access to my original system discs right now or I would try reloading the OS. Any suggestions would be very appreciated, I can't keep checking my email on my phone.
