I'm not sure if this is where you're supposed to go for help, so you'll have to excuse me interjecting myself here-- I'm sorry--

But I downloaded the demo of Vegas Post just to test if literally anything is cheaper/better overall compared to Adobe Creative Cloud

But I can't even get the ONE program to work that I downloaded the thing in the first place for. I don't even completely understand what the error message means.

Before the trial expires, I'm gonna' ask for help because I'm unable to activate the only three tech-savvy brain-cells in my head enough to figure this out.

(I've already tried uninstalling and reinstalling, using the repair feature, uninstalling other programs on my PC to make more room and then repeating the the other stuff, and still nothing is working. All the other programs are working just fine, but not this one. So I it's clear to me now that I'm obviously missing something, so if anyone sees exactly what that is, please help)
