Installed Version 4.16.4; Library contents won't show

[nimbus573]

Hi,
I've never seen this problem before. I just installed Version 4.16.4 on my friend's computer (replacing the earlier version). It seemed to install fine; however the LIBRARY files won't show at all - neither the files from the earlier version, or the recently downloaded songs.

When the LIBRARY page appears, all of the Columns (name, size, etc) are missing. I clicked on "shared files", "saved files", etc in the left side of the screen - but nothing popped up.

When I double-click "View my XXX Shared Files" (in bottom left corner of "Search" screen, all the files are there -- old ones and new ones downloaded after installing Version 4.16.4.

I just can't get them to appear in the Library. Any advice or guidance would be greatly appreciated. Thanks!
