OK. But then I don't understand your problem. I just tried both saves again, with and without mod, and with both I am able to proceed the main story. However, your save is corrupted and may reset at some point, depending on what you do. It even tells you when loading your save that it could not be loaded normally. Loading my repaired save will not give you a warning (because it is repaired). It will also not reset itself.
However, if you load the save (I recommend the repaired one), skip time to the evening, and go to Eric's house, the story will continue just fine. So I can't see what the problem is.
