Thanks to both of you for your responses to my problem. I found out from Roxio support that you could install Creator NXT 2 on 3 machines. Thus I tried a Win 8.1 machine I had with Creator 2012 on it. I just installed the drivers and nothing else. Of course that failed. Next I went to an old XP SP3 machine I have. I installed the drivers and then installed Creator NXT 2 with the USB stick plugged in. As it had done on my Win 7 machine the install seemed to hang (several minutes with nothing happening). On Win 7, I'd killed the install. However on the XP install it was late at night (after US v Portugal in the World Cup) so I just left it until morning. The next day when I looked to see what had happened. Everything was installed and happy. The videos play beautifully on the PC.
All comes to those who wait.
I've now tried to uninstall Creator on my Win 7 machine so I can install from scratch and give it plenty of time. However it won't re-install, just as someone else on the forum reported recently. I haven't checked the log to see if my problem is the same, but I'll try and find out.
Anyway it doesn't matter because in a couple days I'll have all the videos on disk using the XP machine and be ready to move on.
Thanks again for your excellent suggestions and reassurances. You were instrumental in helping me get this done.
