So earlier today I deactivated all my mods and omods, then deleted my data folder. (I have the original from a fresh install backed up,) I then attempted to use OBMM and found out clicking buttons didn't do anything. I tried installing some omods but had to use the enter key to hit yes or no because the buttons won't work. Oddly enough, right click options still work. I have the steam version of Oblivion.
