Thanks quiltgranny,
I am still OK, as I have only put it on one computer so far. When mine crash, they never come back, - so the fact that they will allow many downloads onto the same computer wouldn't help.
I am going to try putting it on my external drive, & use it from there if that works, or maybe a flash drive, which would be more convenient to move it from desktop to laptop. Still thinking about it, - will wait for my techy son to visit & get hands on consultation. That's called kid pay back time, he he.
And yes, I know why they did it, but I would have prefered a dongle, - I haven't managed to lose my pfaff one in over 6 yrs, but in that time have crashed 5 computers! Wow, that makes me feel like the queen of crash!
