I pasted the unzipped URM file in the "game"' folder and started the game, saw the confirmation popup that the URM was installed, but the URM does not open when pressing Alt + MYeah, you could do that messing with the stats. You might have to go back some saves, don't know how much changing stats so late in will affect things, might not be too bad or might screw it up
I'm running Win10Pro and using v10.2 of the game
