Are you trying to load a savestate from 3.0 in 4.0-5163? No wonder it's hanging! Savestates between versions is baaad, even when they are only a few revisions apart, and not thousands! When moving, use the ingame saves for whatever progress you wish to keep, make the move, and make new savestates in the new version.
