iPod Frustrated - "That's not my job."

No one seems able or willing to help with this - Apple says it's a PC issue. The PC people say it's an Apple issue. I'm stuck in the middle.

Any ideas:

On my daughter's DELL Inspiron, iTunes says it can't connect to the Internet, despite the fact that she can connect to any other site. I recently installed Mozilla and did whatever I could to disable Internet Explorer, so I'm wondering if I screwed up the iTunes setting in the process.

I have checked everything I can think of to determine where the problem lies - no luck.

I have - updated to the latest iTunes (4.7), rebooted many times, cleared the cache on Mozilla.

Dotina, thanks.
I know it was the wrong Forum, but I figured heavy iTunes users would be able to help.
YES - I did just install the SP2. Any idea where to look to fix it?

Still no luck -
I've been on the phone with AppleCare and they've given up. Now I need to find someone at Windows or DELL who will answer the phone - HAH.

I have done everything I can think of and still no luck.

with reagrd to the uninstall - do i need to save all the music in the iTunes folder to a separate drive before uninstalling?

I have it on an iPod

FIXED _ After four days of pain

I finally have it working -

Here's what I discovered.

A few weeks back, I was getting fed up with all the pop-ups on my daughetr's Windows machine and I took the advice of someone who told me to set InternetEXplorer to require a "fake proxy" before it opened anything up.

She is using Mozilla, but IE was hiding in the background and just popped up now and then.

Long story >> short: I found that setting, removed it, and VOILA - iTunes works again. We may have the pop-up issue to deal with but at least we'll have good music while we blast away at pop-ups.

Thanks for your help.
