Disappearing apps

[appsboy23]

I have a few paid for apps that worked fine - suddenly when I go to any of them and click on them the first screen appears for a second or two - then reverts back to the main menu.

i did a restore but still happening - any ideas pls?

Here are the steps arn posted in another thread (http://forums.macrumors.com/showthread.php?t=518102):

as people have said, it can be various problems.

The steps are

1) Turn iPhone off and on

2) If not fixed, delete apps from iphone and reinstall (redownload or resync)

3) If still not fixed, restore firmware.

Since you already tried to restore, hopefully one of the other two will help.
