I found then answer to this part of the tutorial. You need to login in to the wallet in online mode then go offline and relogin, then you can get to the export after making the new wallet. Now i'm stuck on the deleting the private key part.
Hey man cheers for the reply, yeah well i tried what you said but when I relogged in i was getting a "Error Downloading Account Settings Template" error...
however, I found that if you log in online,
then click the Import/Export tab, go offline, and then click the Receive Money tab where you can create the new address, it works - you can then go back to the Import/Export tab to print the paper wallet!
Hmmm, deleting the private key, I don't get this either... I assumed that the public and private key was deleted when you logged out offline, leaving only the paper copy you printed. I'm going to try and send a tiny amount to the address on the paper wallet, see what happens and if I can find it again...
EDIT: Right, added my new paper wallet address as an add-only address (by physically typing it in) and sent it 0.001 btc, in theory I should need the private key (which only I have here on this paper) to access it. Hope I'm doing this right haha...
