Applications :: ITunes Asking To Accept Incoming Network Connections Every Time

Because I have Firewall enabled, everytime that I launch iTunes, I get a popup asking me: "Do you want the application "iTunes.app" to accept incoming network connections?" I click on "Allow." But unlike other applications where this process is only asked once, the first time you launch an app, I'm asked this every time.

I've talked with AppleCare about this, and the representative told me it may be because I've disabled "Copy files to iTunes Media folder when adding to library," because I prefer to organize my music folders my own way. She offered 2 work arounds:

1) Enable file sharing of my Music folder. It didn't work. The prompt still occurs every launch.

2) Reinstall iTunes. However, admittedly, she said this may not necessarily resolve the issue as it could simply be because I'm not using iTunes' file location by enabling "Copy files to iTunes Media folder when adding to library."

Does anyone have any idea how to resolve this? Also, if I reinstall iTunes, will I have to re-add my Library to iTunes or are the relevant database/album covers files & folders retained?--it took a few hours for a collection of my size to be added.
