The patch doesn't make the software unusable, just an annoyance closing that window.
As I suggested above, email Smartsound Support (Frank) explaining in detail the problem and provide a screen shot or two.
He's pretty good at getting back to people, and this is information he should have. I've emailed him already about my problem with the 6.6.3 full install.
Smartsound is indispensable in my editing. And it is working so far, just fine, except that that "glitch" that appears as the software connects back to "home".
Mind you, I uninstalled the patched version, downloaded the full 6.6.3 version and installed that one.
