Hi,
unfortunately, I can't get the software to work properly; the Options button does not open any new menu, and whenever I try to upscale a file I get the error message in the screenshot below.
I get similar error messages with all the selectable models.
Could you please assist? 
Thank you!

Hi my friend, the Option button does not open anything, is just a "title" of the option under :)
That error means that the image does not fit in your VRAM limiter option.
You have to select the correct number of VRAM limiter; for example if you have a gpu with 4GB of VRAM you have to select 4, if you have gpu with 6GB of VRAM you have to select 6, and so on.
What GPU do you have?
UPDATE. I saw not from the screen that you have a integrated Intel Xe, in most case for integrated graphics 2GB Vram limiter is the perfect option :)
I hope i helped you :)
