IPod Restore - Error Message 21

Question

Hi All,
Hope someone can help as this is driving me insane - I've just installed iTunes 9.2.1 but when I went to Sync my iPod I was told I needed to restore it.
Sooo....selected Restore but just as it gets to the end of the Restore process I get an error message (21). Having reviewed the info on this website I've tried everything from switching off Windows Firewall to uninstalling my security software.
When I run Diagnostics, this is what I get - PLEASE can anyone help?!?!
