can't update or view log with 1.5

Since upgrading my client to 1.5, I can't update my WC or view the log of
repositories on a particular machine. I have been able to commit to a repo
on this machine using Tortoise. I can view the log of repositories on this
machine using a different client (CommitMonitor). Other people in my office
that haven't upgraded their tortoise client have been able to view the log
and update. This particular machine uses svn+ssh. I am able to update and
view the log of repos on other machines that use http.

When I attempt to update, I get an error "Not authorized to open root of
edit operation" When I attempt to view the log, I get a message box with
title "TortoiseSVN" that says
"C:\Projects\subversion-1.4.5\subversion\libsvn_repos\log.c"
