ipod 6th gen not working in windows 7

[koalaca]

I recently updated to OS Windows 7 and now my daughters ipod will not work. In devices, it shows an exclamation mark under the usb mass storage device and that Windows is 'currently uninstalling' it. I have uninstalled, reinstalled, updated and done every trick I have read to no avail. Everything shows up to date. iTunes recognizes the ipod but I am unable to do anything with it. I tried it on her computer and it didn't work either, as she has Windows 7 as well. I am at a complete loss!!! She wants a new ipod touch for her birthday but I'm afraid to spend the money for fear I will have the same problem.
Somebody, please help!!!! Thank you!

Have you tried to reset the iPod nano 6th generation by following the below method that was given on apple support website:

Press and hold the Sleep/Wake button and Volume Down button simultaneously for at least eight seconds or until the Apple logo appears. You may need to repeat this step.

If the above step did not work, try connecting iPod to a power adapter and plug the power adapter into an electrical outlet, or connect iPod to your computer. Make sure the computer is turned on and isn't set to go to sleep. Try resetting the iPod while it is connected to power.
