I upgraded to 11.4 and get error message -50 when trying to signin. My PC is XP.

I reinstalled iTunes 10.? as could not previously show all new podcasts and apps, only some, this new upgrade showed all new podcasts and apps. But then could not sync at all so I downloaded 11.4, now I cannot signin and get ''We could not complete you iTunes store request. An unknown error occurred (-50).''. Have turned off Windows firewall to no avail. Firewall is not enacted in my other anti-virus program.

iPod touch, Windows XP

Hello there 1Romans1,

In the research I have been doing it seems like this specific error is usually caused by some sort of security software as it secures incoming and outgoing packets. Take a look at this section of the article iTunes: Specific update-and-restore error messages and advanced troubleshooting found here http://support.apple.com/kb/ts3694#error50

Eliminate third-party security software conflicts.

There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. Your default packet size being set incorrectly can cause this error. Contact the manufacturer of the software that installed the packet-size modification for assistance. Or, follow this article by Microsoft: How to reset Internet Protocol (TCP/IP) to reset the packet size back to the default for Windows.

Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online.

There are other steps in the article but they are more for restoring/syncing issues. I feel these are the important ones for your situation.

Regards,

Sterling
