I really, really screwed up.
First, I booted up crusade, went down to controls.
When I saw one word i was confused, so I tried clicking with the down arrow a few times.
When I realized how the system actually works, I realized I had screwed up, so I closed the program to try and cancel what I had done.
When I went, back in, I quickly realized I hadn't cancelled my changes, and couldn't navigate the menu.
I looked through the files, found controls. Upon seeing p2's settings, which I hadn't changed, were all 0, I assumed that was "factory default", so I changed all of p1's values to 0. Now the game doesn't respond to any input at all once it reaches the title screen.
What did I do wrong, and how can I fix it?
