I have DVD Architect 6.0 and 5.2 installed. When I click either one, I get a blue circle spinning beside my arrow cursor for about 5-6 seconds, then nothing. If I open Task Manager, I can see a background instance of the program running...one for each time I've tried to launch it.

DVDA 6 & 5.2 have both worked fine in the past on this machine. Vegas 9 also works fine, but Vegas 12 has typically been crash-prone.

So far, I have unsuccessfully tried:
1. Reinstalling DVDA 6 & 5.2 and restarting the computer
2. Uninstalling Quicktime and restarting the computer

The machine is running Windows 10 Home (64-bit)
It is an ASUS CG5275 "Essentio" desktop (upgraded from Windows 7), w/Intel i5 650 @ 3.2Ghz & 8GB RAM.

Thanks for any suggestions.
