Cannot enter Time Machine hosted on ReadyNAS Pro from Lion

After I tinkered some more with this, I was able to “Enter Time Machine”. Something is definitely wrong with it, though. For one thing, the “Oldest Backup” listed in the Time Machine applet in System Preferences is Today. 7:24 AM”, but when I enter Time Machine, the oldest backup is today at 10:35 PM. Additionally, a few times that I tried to “Enter Time Machine,” I got the following error message:

An unexpected error occurred (error code -6584).

This same error message showed up on my wife’s Macbook Pro when I tried to “Enter Time Machine” from it.

Here’s the latest Time Machine log:
