You may need to reset the driver
and then possibly update your itouch firmware to get it working again....
-Close any other open programs
-Unplug the iTouch and any other NON-ESSENTIAL USB devices from the computer (i.e. PRINTER, CAMERA, etc.)
-Open the iTUNES application and leave it on during this process, you may minimize the program if you'd like though!

-click on your Start Menu
go to Control Panel
click on System icon [computer w a check]
goto the tab that says Hardware
then the Device Manager button (alternatively, u can access the device manager by opening up the RUN command and typing in "CONTROL.EXE SYSTEM" and hit ENTER)
-Under DEVICE MANAGER, click on universal serial bus controlers
to expand the catagory
then you itouch should be in there
it may be under a name like "USB
Mass Storage Device"
then click [up/plus on the toolbar] and choose
the unistall driver option[computer with an X]
(don't worry, your data on the iTouch will be fine!)

-Next plug your itouch back in it should
recognize it
Now then, try to update the firmware through Apple

When an app closes immediately this is known as the app "crashing." The first thing you should do is make sure that your itouch has the latest software update available. This can be done by hooking the unit up to itunes, and clicking the update button. Also try restoring the unit with itunes. You will lose all of the data on the itouch, so make sure you have all your data backed up with itunes. If you have any further questions feel free to contact www.wiredextreme.com.
