sigh. here I am a year later having the same problem. When I try to assign the right side buttons, they are grayed out in icue. I tried keystroke, gray. clicked mouse, gray. I click on the mouse icon and nothing happens. I hover the mouse over the gray box that tells me to click on a button, nothing happens. I try a keyboard key. nope. I click on it with a left click which is the ONLY key it recognizes, but then nothing happens if i click something else. I tried selecting the key i want the function mapped to on the keyboard first, still gray. Tried copying my profile from my old ssd, it copied the profile, but not the assignment. So once again I have no idea how to assign the right side mouse key and have long since deleted his email with the instructions.
