|Ok, I see the problem. Try the following "Error... 1415..." procedure.|
This is from Apple's website:
Error 1415, 1417, 1418, 1428, 1429, 1430, 1436 or 1439: Cannot restore or update iPod in iTunes 7 or later
I know you already reinstalled iTunes but use this Apple procedure as a reference:
Removing and reinstalling iTunes, QuickTime, and other software
components for Windows 7
And you can also try this:
Reset your iPod, when the apple logo appears click Left + Center. It will take you to the diagnostics menu.
Also try this:
Plug in your iPod in Disk Mode: Reset by holding Menu/Middle buttons and then hold Middle/Play until disk mode appears (Leave it plugged in).
Go to Control Panel and open "System"
Click the "Hardware" tab and "Device Manager"
Find and maximize "Universal Serial Bus controllers"
Right click on "Apple Mobile Device USB Driver". Then choose "Uninstall" (If it's not installed, get it with Itunes.) If it doesn't work right there, unplug and plugin your iPod again. Opening Itunes might help.
