Hello, I recently purchased the eval-ad5933ebz. I have downloaded all the files from the website, however I came across the Error saying "Firmware failed to download- Check USB connections." Afterwards I plugged in the usb with the circuit board but nothing happened. I read other posts saying that this installation does not work for windows 7 and older. I am currently using a windows 8. I was wondering if there are any solutions to my problem.
