Itunes crashes whenever I try and open the store

Question

Hello, and this is my first post. For a day or so now I cant get into the itunes store, and when I try to it crashes and I get a report generated that starts like this:
Date/Time: 2007-06-10 19:57:11.850 -0400
OS Version: 10.4.9 (Build 8P135)
Report Version: 4
Command: iTunes
Path: /Applications/iTunes.app/Contents/MacOS/iTunes
Parent: WindowServer [780]
Version: 7.2 (7.2)
Build Version: 3
Project Name: iTunes
Source Version: 7203401
PID: 899
Thread: 0
Exception: EXCBADACCESS (0x0001)
Codes: KERNINVALIDADDRESS (0x0001) at 0xecf967f0
Every other aspect of the program works and I can still buy music from my shopping cart. I have tried reloading the program, I verified the HD, fixed the keychain, did a virus scan using Intego, started a new account and tried opening it thorugh there all with the same result. The rest of my computer programs work. If anyone has any ideas I would be most appreciative, thanks, Marc

Well, now we know it's something likely system-wide. Try a few things:
1.) Completely disable your anti-virus software. Maybe even experiment with uninstalling it temporarily.
2.) If you are connected to the internet via a router, disconnect it and connect directly via your broadband modem.
3.) Disable any firewall software.
4.) Disable any web accelerator software.
