qBittorrent official forums

I had to reinstall a clean windows 10. This time I remembered to backup qbittorents settings. In users local and roaming. I installed Qbittorent , put back the setting files. And restarted Qbittorent. It gave a lot of error messages. Apparently I was not the owner of my drive anymore, so I had to fix that. I restarted Qbittorent again, and he found all my old torrents and seemed to be loading and seeding again.

But the column availability has the number -1 in it? And I cannot find what that means?

Also all the files gave an error in the tracker menu on the left, but slowly those errors are disappearing. And while I am typing this, all the errors are coming back?
