Can't access iTunes Store. 'One Moment Please' message. Please help!

Question

I downloaded the latest version (9.0.3) of iTunes at the start of this week when I bought my iPhone. Everything worked fine & I could access the iTunes store & purchased music. I had purchased music on my iPod which I transferred to my iTunes library & everything was still working fine.
Then a couple of days later I created a ringtone from a purchased song. I synced my iPhone & the ringtone works absolutely fine, however, I can no longer access the iTunes Store. The following message is displayed:
"One Moment Please, Connecting to the iTunes Store, Loading... If iTunes doesn't open , click the application in your Dock or Windows Task Bar."
I have also tried to sign in to my account however I am unable to & receive the following message:
“We could not complete your iTunes Store request. An unknown error occurred (-50). There was an error with the iTunes Store. Please try again later.”
I use a wireless connection at home & iTunes is working absolutely fine on my other computer.
The Radio works fine, I am definitely connected to the Internet as I am accessing other sites at the same time as trying to open the store.
I have not switched to a new ISP & absolutely none of my Internet/firewall/security settings have changed in any way.
I have tried all of the following but none have fixed the problem:
I have configured Windows Firewall to allow iTunes to access the iTunes Store.
I have run Diagnostics which indicates that there is absolutely nothing wrong.
I have removed & re-installed iTunes on my laptop.
I have temporarily disabled my security software and firewalls.
I have using the MSCONFIG utility on my laptop to try & identify if a software program is preventing me from accessing the store but I still cannot access the store.
I am at a loss, I have no idea what to do next…please help, thanks!

Answer 1

Hi I just went through several days of the same problem, I was told to uninstall all of the Apple related software and reinstall in the order on this link
http://support.apple.com/kb/HT1923?viewlocale=en_US
than follow these steps
iTunes Store, iTunes, Windows 7, Windows Vista, Windows XP, Microsoft Windows XP SP2 and Vista
Remove pop-up blockers
Some pop-up or ad-blocking programs may interfere with the ability of iTunes to connect to the iTunes Store. Removing them in many cases will resolve the issue.
Flush DNS Setting in Windows
In some cases, the DNS information you computer uses to connect to the Internet needs to be reset. Follow these instructions to flush your Windows DNS information:
Windows XP
1.On the Start menu, click Run.
2.In the Open field type cmd and click OK.
3.In the resulting window, type ipconfig /flushdns and press Return on the keyboard.
4.You should see a message that the DNS Resolver Cache has been successfully flushed.
Windows Vista and Windows 7
1.On the Start menu, point to All Programs > Accessories and then right-click Command Prompt and choose Run as Administrator from the shortcut menu. If Windows needs your permission to continue, click Continue.
2.In the resulting window, type ipconfig /flushdns and press Return on the keyboard.
3.You should see a message that the DNS Resolver Cache has been successfully flushed.
Note: If, in the command prompt, you see this message: "The requested operation requires elevation", close the command prompt and repeat steps 1 and 2 above to be sure that Administrator privileges are used to access to Command Prompt.

after all this I had to go to control panel and create a new user with administrator controls, log off and on to the new users account. In the new account itunes store finally works, I'm not sure if all of the steps I was first instructed to take were needed, but I was happy to be able to finally access the itune store again. I hope this helps someone else.
Good Luck
