1928 house hardwood floors cupping

We bought this house in Feb, it was cold we are near Chicago. The red oak floors were in good condition but we did not like the color. We had the floors redone and only one room a hardwood floor added. The house was built in 1928 and most of the floors are original. The house does not have central air conditioning, just 2 window units. Last month the floors started to severely cup. I would say 60% of all floors, including the new room, are cupping. We are hoping to get central a/c in a year or two. We constantly run a dehumidifier in the basement, and always have. When we bought the house in Feb. it did seem extremely dry, there is radiator heat. The attic does not have proper ventilation or insulation - we are adding a whole house fan, more mushroom vents and insulation in the next couple of weeks. Will this ventilation help the cupping or is it really from the lack of a/c. The strange thing is that the house never had a/c and we never saw the cupping before - what could the previous owner have done that we aren't doing? Would a dehumidifier upstairs help? My husband does not think you can put a dehumidifier where there are open windows. Will the cupping flatten out in the winter? Thanks!!!
