Make sure the application is compatible with your iPod touch software:
* Check the system requirements in the App Store.
* Check your iPod touch software version using Settings > General > About.
If the application requires a newer version of the iPhone OS than the one you are using, use iTunes to check for available updates

For issues downloading or syncing applications, make sure you are using the latest version of iTunes.

You have to Update your applications to fix this problem. On iPod touch:
Open the App Store and tap Updates. If updates are available, tap Update All.
When prompted, enter your iTunes Store account information. iPod touch will then download and install the application updates.
After this you will not get any problem.

Have you tried to Restart your iPod touch? To restart iPod touch, first turn iPod touch off by pressing and holding the Sleep/Wake button until a red slider appears. Slide your finger across the slider and iPod touch will turn off after a few moments.
Next, turn iPod touch on by pressing and holding the Sleep/Wake button until the Apple logo appears.
