Adobe Cloud reader unable to show documents

Hi i recently updated my adobe acrobat reader DC, I usually highlight and save my pdf both on my computer and on adobe document cloud but when i open it on my computer documents the highlighted ive done is gone. This never used to happen as the highlights after ive saved were always there, however, when i go into my RECENTS on the adobe reader, the highlights are there but when i try to open all my documents under document cloud the screen goes blank and i dont have access to any of the documents on cloud. I really need to find all the documents ive lighted since ive worked hard on all of them.
