That must have been the difference, I did switch to 2.0 at some point.

Again, thanks for the help!!

That was absolutly it! Thank you so much.

When did this change, I used that disc for calibrating for years and years.

thanks!!

Im having the same issue above as FOCW. I cannot for the life of me get the target to be green. I have a new laptop I have set up everything up exactly as the guide goes and an older desktop that was working around 2018, but the desktop has the issue now as well. Nothing has been updated on the desktop and the calibration disc is the same one I created in 2015.

Any help would be great!
