Unable to load iTunes Store

Question

Since the Apple support staff has proven themselves utterly incompetent, I was hoping I could find some help on the forums.
I am attempting to go to the iTunes store from the iTunes x64 Client (RC 10.5.1.42, the latest) on x64 Windows 7.  I am unable to because the page does not load, as if it times out.  No error messages are returned, and the client does not visibly change.  When I go to view my account in iTunes, it shows as a plain-text version of the site, looking like basic HTML and form buttons on a white background.
I have run through all the kb's I could find, and then succumbed to contacting customer support.  They then kindly told me to download the latest version of the software, which I had done three times already, including wiping my registry, temp, and app data of all Apple products/keys.  Then they told me to run through all the kb's, which again I already had, as they claim it's a connection issue on my end.  Clearly it's not, and I am attempting old versions of iTunes now just to verify this claim.
Here's the log:

Answer 1

I am having the same issue and have spent close to 18 hours between Apple Support, my Security IT Department and Versizon FIOS trying to fix my problems.  All was well with my ITUNES account which I had previously synched with IPOD's and an IPAD2 until last week.  I tried to synch a new IPHONE 4S and have not been able to access my ITUNES store ever since.  I can access the store from my IPAD and IPhone but not from my Windows XP PC (or from 2 others).  I click on the IStore and my PC freezes at the same spot which is always the same spot about halfway along the ITUNES bar.  I've uninstalled and installed new two times.  I installed new for the very first time on a personal laptop and I have the very same issue.  One Apple support advisor claims its my PC Security Software causing the issue and another claims its my Verizon FIOS configuration,  neither of which had changed and worked perfectly until downloading 10.5.  I can't get to older software versions so would like to know where others are finding them.   I also have the same issue when accessing my account data which displays plain text without any HTML.  There are links but they do not work.  I have run all of the diagnostics and pass each time.  I am so frsutrated at this point I'm ready to return all of the Apple devices!  If you find a solution, please pass it along and thanks!
