Blank Screen on Demo Software

I'm evaluating the Pro software on my P3D, so it's still within the 20 day period.
When I first installed it I was able to access all the screens and facilities. Now when I activate it, it clearly does add weather to the sim, but the FSrealWX screen remains blank.

I can't. The product icon is on the lower taskbar as being operative, if I hover the cursor over it it creates a small screen of the product over the taskbar, but will not expand to full screen, no matter what I try.

I have uninstalled and reinstalled, to no avail.
