Lightroom files missing, not syncing to cloud
Today I tried to edit an older file in Lightroom CC but the controls were greyed out, indicating the original was missing. I tried to edit in Photoshop and got the message: "Edit in photoshop failed. Unable to download original or smart preview. Your computer is offline, going online will allow you to download files." Not true- I was online and signed into CC.
Next I went to https://lightroom.adobe.com/ to see if the original was there. Not only was it not there, but NONE of my originals were. In my preferences, I supposedly have over 40000 photos, which take up 11MB.

So it appears some of my originals are missing, and none of them are syncing to the cloud. Help!
