Ok, so that nightmare is over. I had time to come back to this project. I took the original sd card that came with the duet and plugged it in my pc just like last time and for some reason it let me look at the files. Last time it wanted me to format the card and i never did. So then i just dragged the sdiap_MB6HC.bin file into the folder where needed and that was it. Why that wanted to work all of a sudden i don't know.
Finished uploading the rest of the install in web control and is now 3.2.0.
Thanks for the help
