I just realized today that my one computer hadn't backed up in over a month (other one is still working fine). When I logged into my backup account, the computer is showing as offline even though it's online (it's the one I'm using at the time). I followed some links here and it recommended doing a reinstall of NOBU to fix that. Unfortunately, that created a new computer and did not link the old backups to the new computer (and no, I did not uninstall NOBU before doing the re-install).
This isn't that big of a deal by itself. I had enough storage space to run a backup of the "new" computer without deleting the old one. Now that has completed successfully, I'd like to get rid of the other one as it's taking up space and causing me to get low space warning messages. I initially tried a purge files (selected all files). I have no idea if a purge is running because nothing happens when I click Purge Now. No error, no "in progress", nothing. Might as well have clicked a blank area on the screen. I then tried to remove the computer. Same response to clicking the Remove Now button. Nothing!
If there is a purge running in the background, I can't tell (maybe the first attempt started something).
