I've had this problem with Continue being grayed out - almost everytime I start up - I found a solution which I wanted to share because there are so many posts and not many solutions. It seemed to be random at first, and sometimes a restart made it work. But now it seems that if I have too many saved games it happens - so I go to C:\Users\User\Saved Games where it appears my saved games are for this - which might be the problem - however, I just remove a few earlier saved games and it starts the first time. Hope this helps someone because this is truly an annoying bug that has been brought up - for years and years and still no fix...
