Are you using Skins? Have you tried importing on a clean library.
What files do you have imported (jpgs, wmv, http://). Are they in local format (C:\,D:\) or UNC (\\Computer\).
Anything you changed from the default installation?
I'll think of some more stuff.
I did some fiddling around with skins prior to The Big Accident. Not many of them appear in the recent installation (Green Eyes, PixOS, Tekno and Z). Don't know what you mean with importing on a dean library. I haven't imported any other files than a few jpeg files (album covers), all kept in the C:\Programfiles\JRiver\ etc folder.
