Installation missing halo 2 and 3 and halo 5 beta

I finished my installation last night and today i come home to see i cant play halo 2 or 3 campaign because a screen pops up saying theyre 25% and 0% and 12% installed.
ive left it on all day and nothing has changed, how do i get these 2 games in install and also i was told an update was released thats 20gb yet nothing came up when i put my disc in to get this update to start

Try doing a full restart on your installation. Uninstall then re-install again. I know it sucks but it should work.

yeah im currently reinstalling the game atm , already on 19%(ready to start) so not complaining, just hope all campaigns are on it after because that was disappointing to see when i wanted to play but could only access halo 1 and 4

is it normal for it to say queued through out it and its been on 35% for a bit now
