A problem I discovered just recently with my Viking embroidery machine which is 10 years old, is that I can't use any computer operating system newer than Windows 7 (I think that one).....to read designs from the computer....if I used cards, it's fine, but those are spendy. I figured out that's why there seems to be a lot of used machines out there, many older machines must have this same issue. So it kind of sucks, because I don't want to fork out big bucks for a new machine, but i still want to embroider........sigh....and i don't want to have a computer that isn't updated.....sigh
