Hi Emil,
You should be able to go to the Restore tab, expand the tree to find the backup that you need. For example: let's say it's on Computer A and is on the D drive. There should be an entry for Computer A, expand that, find the D drive and expand that. Then you should see a list of backups by date. Find the one you want, expand that and keep expanding until you see the file you want to restore. Click (check) that file and then restore it
