To be certain, I ran the Welcome Wizard again, making sure it was pointed to the Calibre Library folder, but to no avail. Any other suggestions?
To show the books in the GUI, Calibre doesn't even need the books - it just needs the metadata.db. If you have that file on the new machine, and you have Calibre pointed to the directory that has that file, you will see books in the Calibre GUI.
If you don't see books, the first step would be to verify that you have the same metadata.db file in both places. Take a look at the file sizes. An empty metadata.db on the new computer would be smaller than the one in your original library. If they are different, just copy over the bigger one to the new machine. If they are the same size, then you probably don't have Calibre pointed to the correct folder.
