Ok, I'm installing on a laptop and the computer was completely locked up, so I removed the battery after unplugging the computer. That shut it down completely and the reboot seemed normal. Stamp Manage 2017 asked for the activation code and all seems to be ok! I still have not seen the video, but it seems I did everything right.
Thanks for your help

For those of us who cannot rely on the internet to download Stamp Manage, It would be very helpful if you would supply the Getting Started Guide in printed form as before. I'd be willing to pay more to receive it.
