Hey sick, as it turns out you were right about not having a mod installed. For all of those having the game freeze when they click on the continue screen or to load up a mission your most likely missing a mod the campaign is dependant on. I used the console to unlock all the missions in the campaign and selected replay and the game at least tried to lauch the mission but was unable to do so because i didnt have robert hammers mk_18 mod installed. So for those of you having trouble identifying what mod you are missing give this console trick a shot.
