I tried this just now. Downloaded the .1 version, and ran it. This time, it showed that it was writing, and then hit the "done" at the end.
Unfortunately, after it was done, I checked the card, and it seems to have lost its formatting, and now shows the card is fully used, no free space, but at zero bytes, whereas before I ran it, it was an 8 gig card, all the space was free.
So this doesn't work for me, either.
I had to download the older version of Win32. I tried version .2 over and over again to no avail. But once I deleted that and installed version .1. Ran it and boom, worked fine.
