3004 error when updating my iPad with the latest software

hi Guys as heading suggests I have a 3004 error after loading my iPad with an update.

My iPad screen shows the itunes icon with a image of the plug in cable just underneath it.

I have turned the iPad off and on, I have turned the PC where my iTunes is off and on, I have check for further updates and I have ran Fix it for Windows 7 and I still cant get itunes and my iPad to align as being completed and up to date.

Any suggestions?
