I had three sync´d devices- two pcs and a phone, on the basic plan. My main pc died. I have rebuilt a replacement PC, and went to install dropbox. It asked me to remove one device (limit of 3), so I removed the main pc from "sync". It said the files would still be available, but no longer sync. But now it appears to have made those files unavailable. Anyone know how to revert the settings so I can see the pc backup which I removed from sync? Very grateful for any wisdom!
