Cant update, restore or sync

Question

I am having similar trouble to someone who posted a topic on Feb. 11th but there were no replies.
When I plug my iPod into my computer and bring up iTunes I get an update alert for my iPod to update to version 1.1.3 and when I go to update it starts to and then a window pops up and I get a message saying "The iPod could not be updated. An unknown error occured (1417)." And then it ejects my iPod from iTunes. When I plug it back in and opt not to update I try to "Restore and Update" the iPod and when I do that the same thing happens except I get the message "The iPod cannot be restored because it contains files that are in use by another application." The window also shows that there are 100 songs that could not be found. A couple hours ago it was only about 60-70. I'm not sure why more and more are turning up "not found". I even reset the iPod and tried synching again and the same thing still happens. Please help!?!?!?!?!?!? I have tried ALL the suggestions in the "unknow error report for 1418, 1417, etc. but still no luck.

i found this answer on a previous post on this same topic.
Use this tip at your own risk. If it works on my PC, it can work on yours.
For the ones having that iTunes problem, which iTunes recognizes the iPod but doesn't sync and shows the message "iPod cannot be synced. Required disk cannot be found" or ""The iPod could not be restored. An unknown error occurred (1418)", here's my advice:
1 - Read the Apple Troubleshooting article available at http://docs.info.apple.com/article.html?artnum=304996. Try every solution, even the one saying "Try deleting or removing any third-party Windows OS skins, Windows themes, or desktop mods that are installed(...)". Yes, you should uninstall VistaMizer.
2 - Still not working? Try reinstalling your iTunes, but backup your library first.
3 - And finally, the solution which really worked well. Disconnect your iPod, close iTunes. Remove the iPod from the dock, open "My Computer" and leave the window on a visible spot. Place the iPod on the dock. Check if any new removable drives appear. If it does, keep reading. If not, then I'm afraid I can't help you. Now that we can see the iPod drive, open iTunes. POINT OF RESTART Put the new songs you want, as many as you want, or delete the old ones, do something to trigger the automatic syncing by iTunes. The software will try to sync, and it probably will show the same problem as before. Don't panic, everything is fine, don't use CTRLALTDEL, please. Just close the window displaying the odd message when it appears. Leave iTunes open, displaying your iPod content. Go back to the "My Computer" window. Leave it on a visible spot. Now let's start the magic, go to "Start" -> "Control Panel" -> "Add New Hardware". Click on "Next". You will see your iPod drive reappearing on the "My Computer" window. Just return to the iTunes window, click on "File", "Sync iPod" and it's done. After syncing, the iPod drive will disappear from the "My Computer" window. To sync again, repeat the operation from the point of restart. To eject your iPod, do it as you would do on a normal operation.
That is just a trick, but it works perfectly while Apple doesn't release a bug fix. Forcing the detection of the iPod drive was the only solution that I found after hours trying to make my brand new iPod Shuffle work.
