Disklavier

Perhaps someone can help? I recently downloaded DKVBrowser which looks 
fantastic. I can connect to my MarkIV but when DKBBrowser starts, the 
entire database list of albums, songs from the Disklavier MarkIV is 
empty even though the hard drive has many albums on it and plays fine 
from the remote PRC. Am I missing something here? Thanks very much for 
anyone's help!
