Tried Cura 5.2.1 and at first it worked well printing good quality prints on my CR-10 printer. But after 4 different successful parts it now refuses to load a .stl file at all. Just saying unresponding. Tried reinstall several times but same thing. Tried going back to v4. 8 but same thing. What do I have to do to get it to work again please?
