Issues Playing Arma 3 Campaign

[cring0]

So, I've yet to actually play Arma 3 itself, so I decided yesterday I would try to finish the campaign.  However, when I would get to checkpoints and such, nothing would happen.  There was no dialogue, the characters weren't doing what they were supposed to, and it would just give me a mission failed after sitting there for 15min not doing anything.  Figured, "ah, I didn't unload Epoch from expansions.  Did so, and now when I try to start a campaign it's saying I'm missing Epoch files...  So, I tried reverifying the game, the only thing left that I can think to do, and it doesn't find anything wrong.

 

>_>  Arma, oi vey.

 

EDIT: Nevermind, I just had to restart the campaign.
