My files seem to be missing. OMG

Windows 10 user. Two days ago my PC crashed and a technician had to wipe my drive and reinstall Windows. Today I logged in to Adobe CC, downloaded the desktop app and the two programs I use most, Illustrator and InDesign.

In the desktop app, I clicked on files. It says I have no files in the cloud. I thought I was going to faint. I hope that's not true. There was years of work there. My business.

Hope someone can help me.
