Hi, Zak, and thanks.
I went through your steps above (including the 55014b update), and was fine with the sequence until I got to here. But when I click "Play Game," I still get the distorted, neon-tinged game window, rather than normal graphics. (See attachment.)
I also tried to bypass and get to "Options" because I could still make out the text on the button ... but then I got what you'll see in the second attachment: an interface blown up so big that both the top and bottom of the window (the most important parts, of course) are cut off. (I'll send that in a second message.
So I'm kind of dead in the water. I checked the Matrix website for additional, more recent updates (like the 2018 patch for "Last Stand: Arnhem"), but struck out there, too.
For specs, I'm running a Lenovo ThinkPad X1 Carbon with Win10 (64-bit).
