Dialogue Error

[Speff]

When I play Halo CE and go in a multilayer game, the dialogue such as "* has entered the game" or "* was killed by *". For me, none of that shows up. Even when I press a button to type something, only the grey box shows up. It doesn't even say "Vehicle" "Team" or "All" in it. Any suggestions?

Things Ive checked:
I tried it at the lowest resolution. No change
I tried re-installing it...5 times
Restarted
Tried another map
