Updated, now project files gone

[Mr. Torture]

I have not turned on my computer in a few weeks, I fired it up and started Cakewalk. It asked me to do an update which I did. Now my project folder is empty? I can find other project files on the same drive and other drives, but the specific folder is completely empty. I know it's the correct Cakewalk folder and it did not change the location in settings when it updated?
