Key bindings always revert to default

Have had this issue since yesterday after H2A’s release. Not only can I still not see the message of the day in a language I can understand, my key bindings no longer stick and I have to manually adjust my sensitivity and bindings for Reach, CE and Halo 2 every time I boot the game. Has this happened to anyone else? Is there any way to make the key bindings stay in the settings?

I always have a binding issue when a new game comes out. Unfortunately the only remedy is to like you had said, manually set everything back.

Mine is resetting keybindings and control settings to default as well. This started happening after the H2 update. I tried deleting some settings files and verifying my game files but nothing has fixed it.

Very frustrating.

The only workaround I have figured out is to avoid looking at the settings at all costs. Still reverts randomly though.
