Hello! I have just upgraded to Vegas Pro 17, and after I go through installation and registration, the starts to boot, but gets stuck on ACBoxCombo.dll. This is a VST dll from Native Instruments apparently. How do I overcome this problem and use the software I just paid for? I am running Windows 10 Home v.1903, build 18362.592. My lptop is a Lenovo Yoga 2 Pro. I am blocked from working, so this is a high priority for me.
