Problems updating my iPod Touch

[cotton31]

When downloading the 1.1.1 update, iTunes downloads the whole file (I assume so, the bar fills up anyway!) and once it has finished I get an error -

"iTunes could not download this update. There seems to be a problem with your network connection. Unknown error (-48)."

There isn't a problem with my network connection as all my other downloads are working fine. This happens whether I click 'Download Only' or 'Download & Install' when i'm prompted to update.

Been googling this for ages with no luck - can anyone help?

(BTW its an 16gb Touch, iTunes 7.4.3.1, Vista x86 (I know, I know!), if that helps?)

Thanks.

I have, but will this not cause problems with transferring song and the like?

Just saying it is wrong. Like having a cheese and custard sandwich.

In the process of saving up for a MB.
