Apps won't open on my itouch?

My itouch apps arent working. They open and close?

• I just got an itouch yesterday. the first thing I did was plug it into my laptop/itunes. While Itunes was upgrading i downloaded the facebook app and pandora through the device. It was working fine. once the upgrade was done I synced the ipod as a new ipod and got all my music on it. after that every time i tried to open one of the apps that I added it would open for a quick second and then close. I have tried to delete the app and reinstall it. delete it and reinstall it via itunes on my pc. i reset the itouch a bunch of times. nothing seems to work. anyone know how i can fix this?

• Answer:

  perhaps try and plug it into your computer then putting it into DFU mode then resetting everything then try putting it all back on hope i helped :)
