I have had the same problem, and now I stay on that site while I open the zip as soon as I download it. If it says, "Damaged or Corrupt" I return to the embroidery site and redownload the design. When I file it, "Do You Want To Replace The File" appears I click "Yes". It usually will open with the second try but once in a while I have downloaded a design a third time before it will open for me. Good luck. I hope this will translate well into French for you. hugs
I meant to say that I have had the same problem on different sites. Of course if you bought the design and notify the digitizer that you can't open it, she or he will send you the design again. It's a "Corrupted in Cyber Space" problem and not the digitizer's fault.
