Glad to know your back with all your original songs.
If you still want to import zip files to your database bear in mind the Merge duplicates button won't merge files that have an identicle DiscID to files that already exist in your database, it only merges songs that have an identicle Book Id.

Now to avoid the chance of importing these duplicated Disc Id's I would say it's best to import them from the Index HD Files dialog (Import Songs tab then Index HD Files button) rather than the quicker Build songs database dialog, this is more time consuming way but will enable you to check the files before they actually import. Also select the Single rather than the Batch option again so you can monitor what is being indexed.

Now if you don't care if it imports duplicated songs you can set the Field & track seperator boxes for Disc ID and Track to Ignore, then either enter your own unique Disc Id in the box for DscID (this could be the original Disk id but with an added # or letter on the end to make it different from your existing) or leave Hoster to create it's own which would be something like XYZxxxx. It will then import upto 99 tracks per BookID.

Should you not want it importing Discid you already have then select the Disc id and track fields in the seperator boxes correct then check before pressing the import button that the disc ID is not already in your database. I'm not sure, you may see a message that the disc id is already in use other wise manually check before importing. When you find the duplicated files you may want to open the folder in explorer and either move them to another folder or delete them so that they do not keep appearing in the import list.

One other point before you try re-importing these zips, Open the folder containing them in explorer, if they have the kmh files still with them from your previous attempt at importing them, delete the kmh file. To make this easier right click in window select Sort By Choose "Type" if you don't see Type listed select "More" then tick the option in that dialog.
This should list all the kmh files seperated from the zip making it easier to delete multiple selections.
