@Merc
I've just read on another forum someone asking about the same thing, no answers there yet though.
@Turambar
I've just had a quick look at that link, but I have no idea where I should go from there to get the patch. Could you give me a direct link to it? Also, do you know how big the patch is?
@Blomberg
I don't think they have a firewall installed yet - they (well, me really) were going to install WinXP again as they are having a few problems with it, but I don't have the time to do that just yet.
Edit: just seen Floid's post, very helpfull indeed :-D
Edit2: how do you find out if you have the 32-bit or 64-bit version of XP? (I think it's Home Edition she has btw)
