Err, I have done both the installs, and neither one of them had a *.azw2 file anywhere...?
EDIT: Doh, the whitelist. I'm a fool. I added update_ss_trial to the whitelist and she worked. So far no go on the connection, but that's probably because I'm a VNC noob. I will be hanging with some geek mates this arvo, and so will give it a go then.
