Problem Terminals

On halo 2, trying to log into a terminal is hell. It goes to Halo TV but then right back into the game and makes a beeping noise. Are some of them difficulty sensitive?

Not as far as i know bud. Im going through on heroic and unlocking for me although for most of them it glitches to black screen when going to halo channel. Press b to go back to game then access terminal again , usually works then. Terminal on heretic i think is glitched for me tho. Will not let me access it.

I’ve unlocked many terminals through 1,2 and 4 and it goes to the halo channel load up screen and then black screen with the loading circles only for it to go back to halo. I’ve tried many times to go back to them and try to reload it to no prevail! only thing I can say is try to play that mission again on a lower difficulty and see if it works. also I noticed that when that happens I have to complete the level otherwise if I try to save it and go back it wont load up at all (only halo 2) don’t know if anyone else has had this?
