Thanks for your reply. Yes, I have tried this but no joy. The home page opens but Photo Editor won't. No idea what to do - bought the software but it just won't work - a very expensive mistake. Will have to ask for a refund somehow.
You may need to uninstall and re-install. Try using a different installer such as the trial version (it’s identical to the full version) and after installation activate with your serial number starting 1057.
