ED installs, but doesn't run

I'm really enjoying Stardock's Object Desktop. Thanks folks!

I'm running Windows XP Pro x64 and have had a few problems. Window Blinds 5 wasn't skinning all my programs, but when I switched to version 4, all was fixed.

My current problem is that ED works great on my XP Pro x32 system at the office (and I fell immediately in love with it), but I can't get it to work on my x64 version of XP here at home.

I've uninstalled and installed it twice, but nothing works. The help files won't come up, the only change it makes to dialogs is that it will successfully hide the windows 'places', but that's all. It won't replace them, won't add the favorites to the top, or do anything else.

This is really frustrating, because its functionality is great and I'm lusting for it here at home.

Thanks in advance!
