did you put in the USB drivers ?

The are two files that must be had, they should be in the folder
if not, I posted the two files in the files section, the instruction are with them

Yes I have files....I have even delted and put them in again. It goes to 25%...then nothing. A couple of times it read card then not detected when I try to erase. I have been reading and working on this card for weeks

Make sure they are in the USB atmenga folder
try adding the in windows
system - system32

that works for me, that is why I posted them

[scamperbj]

Bad card. Contact dealer for swapping instructions. Stopping at 25% is the give away.
