Can't move on menu [Stepmania 5.0.9 Mac]

I seem to can't move on the menu for Stepmania 5.0.9...
It used to work fine, but when I was messing with options, I must've messed with something that might've caused my problem..
All I can do on the menu is Select,
I can sort, and change difficulty but I can't move on the menus.. Is there a way to fix it?

I've tried uninstalling and reinstalling Stepmania but no luck...

Sounds like you turned on the Only Dedicated Menu Buttons option. It disables using the gameplay buttons during menus. home, end, pgdn, and delete should work for navigating the menus to turn it back off.
If that doesn't work, you can find ~/Library/Preferences/StepMania 5/Save/Preferences.ini and edit it to turn the option off with "OnlyDedicatedMenuButtons=0".
