Karaoke Home Producer

[pedeedog45]

I just bought the upgrade to Karaoke Home Producer. I did all the downloading, installing etc. without any errors that I knew about. When I was done, I tried to get into each one, and every one said "serial number does not match registration number. Please reinstall. Does that mean I need to uninstall evey one and reinstall all? I have looked everywhere on my printouts and I do not see a serial number anywhere. It seems weird that all of them have the same message, and where would I find a serial number? Help
