Running LJArchive

I've backed up my own LJ using LJArchive with, apparently, no problem; however, when I try to back up tim_maroney, I get this error:

"The server requires that you set your encoding setting before your journal can be downloaded. This setting can be found at your journal's web site, at the bottom of the 'Edit Personal Information' page in the 'Auto-convert older entries from:' box."

Any idea where to actually find this box?

ETA: Solved! Here's a link from smofbabe.
