ITunes 10.5 won't update files properly on my iPod Touch 4G running iOS 5, how can I fix this?

Question

I recently updated iTunes to 10.5 and my iPod Touch 4G to iOS 5, but now when I try to edit the ID3 tags or artwork of songs on my
iPod using iTunes, iTunes just says "Preparing to update files" but it never actually updates them. When I try to add songs
manually to iPod (my iPod is not set up to sync music with iTunes [see note below]), the same thing happens, with the newly added
songs appearing on the iPod library but are grayed out with a still loading icon next to them. Also, in some instances when I try
to change the artwork of all the songs on an album, it grays out the songs I tried to change, puts an exclamation mark by them,
and applies those changes to other songs on my iPod! And if I delete the songs I attempted to change it deletes the songs that
were received the artwork change. The songs that were unintentionally changed somehow got overwritten by the songs I was trying to
change while retaining the original tags of the songs that were changed. Not sure if I'm explaining this clearly so let me give an
example: song A is a song on an album on my iPod, song B is on song on a completely different album on the iPod. When I change the
artwork on song A, it somehow messes up my library and song A overwrites song B, but it keeps all of song B's ID3 tags. So I don't
know song B is song A until I play song B, at which point the ID3 tags are changed to the tags of the song A, and song B is just
disappears. This only started happening after updating to iTunes 10.5 and iOS 5. Not sure if the problem is caused by iTunes 10.5
or iOS 5, but I did search online and found someone with the exact same problem effecting their iTunes 9.1 (no iPod involved). 
Can someone please tell me why this is happening and how I can fix it?
Note:
I add songs manually to iPod because I don't keep my music on my PC and sync my music with iTunes because it would take up too
much space and I want to be able to add songs on my iPod from other computers. Once you set it up to sync music I believe it
disables making any changes to your iPod with iTunes on other computers.

Answer 1

okay, I don't know about the rest, but about the songs never actually loading onto your iPod, I found in another discussion how to fix that. I'm using Windows 7, so I don't know if the steps are the same, but the end result is the same. So go into your Start menu, then into accessories, right click 'Command Prompt' and click 'Run as administrator'. Then type in the following: netsh winsock reset then press Enter. After a few seconds it should tell you to to restart your computer for changes to take effect. Restart your computer, then restart iTunes, then everything should be working fine. It still takes forever sometimes to update the iPod, but eventually it will work. I've had to do this multiple times, so I'd suggest copying & pasting this solution into a notepad or Word document and saving it on your computer, so you don't have to go through the discussions again to find it. This tends to happen to me nearly every day unfortunately Hope this fixes that problem, but I'm not having any of the other problems fortunately, except for removing the artwork of the songs it updates without me asking it too. PS I think my problem may be with iOS 5, because iTunes 10.5 came out before iOS 5, and I think everything was fine before I updated my iPod, but I really don't know where the problem lies
