After installing Plucker it didn't show any documents. I tried to use function "Add" to one document but nothing showed in the main page. After restarting program, there was the same document which I added in the main page,which could be opened and read. So I added every Plucker PDB file I had (four documents/in MMC/from memoware) one by one with Add-function and restarted Plucker. Voilá, my four book library was ready to be read!
