Disappearing huge amount of files from Creative cloud sync

[#1]

Hello,

Recently I've made login on CC in a second PC, and I noticed that a big amount of files have been disappeared while syncing.

Second I was looked on the Recovery section in assets.adobe and any one of them were there.

In third, into assets.adobe I was used the search functionality and the files appear, but when try to see or download return 404 error.

By the way I've think "let's turn on the first PC and make a backup of the CC folder", but in the moment that CC made login all the disappeared files where deleted too.

Looks like all the files unused by more than a year are gone.

And now? What can I do to re-see my lost files?

After some search I've found this help Re: Some files disappear off creative cloud

All desappeared files where gone to Recycle Bin... Don't know why, but I confess it scared me a lot.
