Thanks for the welcome message.Yes its as I thought.Am in the process of trying to get LH 4015 but its so slow through Bitorent.Have also tried some ftp sites,but cannot log in as they are always busy.When I eventually get the iso I will attempt to do a clean install instead of an upgrade.
My mistake in trying to do an update when LH is still in alpha.
Thanks again for the advice.

cheers
