ITunes does not show Shared Music and cannot listen to Radio

Question

Hi, I would really appreciate some help on this issue - thanks!
In itunes, the 'Shared Music' folder on the left side panel simply does not exist no matter how many times I check/uncheck the 'Look for Shared Music' in configurations. In addition, I cannot connect to any radio stations listed.
I have no trouble accessing the itunes music store and other online features, so I do not think it is my internet. That said, I fear it maybe my norton internet security software thats causing these problems. Just to be safe, I have given total permission/access to anything itunes related: Itunes.exe, itunes music helper.exe, quicktimeplayer.exe, QTinfoapplication.exe and QTtask.exe. Also, I have (to no success), installed Bonjour services from apple and also Rendezvous Proxy. So yeah.. I am pretty much out of ideas.
I live in a college environment, so I'd really like to check out other people's music. My friends on both PCs and Macs do get this problem at all. In addition, before the itunes 4.7 upgrade, I was able to access most people's shared music. However, with additional upgrades, i noticed that my shared music list would dwindle from say 50 to 20 then 10, etc until it reached nill! Pretty scary, so your help is totally appreciated.
Thanks for reading!

Answer 1

ok b noir I don't have much time but, idt it worked. But, let me explain. Some of the files I didn't see in the registry like the ipod manager. I deleted some of the ipod services and all of the other files I saw that had the word iPod. But, not all of them. There were also many files that were iTunes files. IDK if you wanted me to delete those too.
I did the whole thing restarted it and then opened iTunes and iPod updater. I hoped and hoped that it would work. When I plugged it in. THere were some "Pop" sounds. You know the sounds that usually come up when you add new hardware. But, nothin' came up as a bubble from the taskbar. Just a couple seconds later a message appeared. And this is it: "Windows has finished installing new devices. The Software that supports your device requires that you restart your computer. You must restart your computer before the new settings take effect. Do you want to restart your computer now?" and that's it. The iPod isn't recognized by iPod Updater or iTunes that I have opened.
So if you could tell me what I may have done wrong. Thanx and goodbye.
P.S. This was updated but I tried it again and I couldn't find the ones I needed like iPodmanager and all those. I have the thing that allows me to see hidden files but, I couldn't find them. So I deleted everything that had the name "iPod" and a few files that were iTunes files. I restarted it after downloading iTunes and iPod updater. I plugged it in, nothing. This little thing at the bottom popped up about the new software. That usually happens when it doesn't work. And it said that if I didn't restart it, it wouldn't work properly like it usually says. So I restarted it and when I got back I plugged it in again and the folder with the iPod stuff popped up, which also means that it didn't work. THen I thought about the format because it may have that same problem. So i formatted it in FAT 32 and it formatted. I also put it in disk mode before I formatted it. nothing happened and it still wasn't recognized. Please help.
