Using the options on the log-in page, (which I could thankfully see) I changed the size to my screen's resolution 1920x1080.
But when the log in page of Icon loaded, I was greeted with a very small resolution, only taking up the middle portion of my screen, it also had cut off most of the log-in screen. It all downloaded fine and I launched Tequila and from there, Icon. I recently got a new laptop and had to install both CoH and Icon, via the link on the Paragon Wiki.
