Each game has its own trainer, you are using the OST trainer which will not work for the others. Please actually read the trainer names.
if its worth anything, I did submit this request myself. Just waiting to hear back about it.
All the games except Halo 2 git a slight change other than the "no more achiv's" Tried them all and sent Caliber a list of each MCC trainer error.
You may have sent this, but I guess I am going to have to have a master list of how many campaigns got borked in the last update.
I already had to rewrite COMEPLETELY the entire trainer for Halo Reach. If I am going to have to do this for EACH CAMPAIGN now, this could take a lot of time, and frankly my willpower in this title is waning.
So if someone wants to test the trainers for each campaign on the latest revision of the game, and then post me a PM about which are broken, then so be it.
RIght now we have no good way to report campaigns being broken, as the site decided to allow you post trainer needs up date for MCC as a whole, which isn't helping me much.
you are posting this in the halo reach boards, so you probably are running the wrong trainer as well then, please make sure you use the correct trainer as each game in the collection has its own trainer..
