Are you talking to Pinnacle on their help line. They are absolutey crap (sorry FE - work for a computer co and will sign an affidavit to this effect!!). You need to talk to Pinnacle UK direct. Can you supply me with your email address and will advise you of the person you can speak to.
Pinnacle software is really good but a pig if anything goes wrong. Uninstalling in most cases does not work as you also need to hack the registry.
