I keep getting this pop-up with Platinum, and when I click on it I get directed to web page that doesn't exist. Yes I have run the program as ADMIN, but it never prompted me for a challenge/response code like previous versions.
 
 

Did you try a reboot?
 
That's what cleared it up for me the one and only time it happened here right after install.

I will try it, only seems to occur when I'm dragging stuff from the browser.
 

Did you install with the CCC?  Or otherwise?  Well, I guess what I mean is, how did you download/install it?

I downloaded it to the specified directory, but then ran the installer myself instead of letting CC do it, maybe that's the issue. I will experiment some more. At least I got the Melodyne issue solved thanks to the other threads.
 
 

Let us know how it goes!

Thanks scook. After a day and evening of work, this appears to be a phantom problem, it hasn't cropped up again and I've been able to save and export files so there's no way this is running in demo mode. When I open the About tab under help it lists my full serial #. If it happens again I'll do a trouble ticket for the tech support people.
