First off, the first error suggests you look in your file "users.php"
and that you're specifying an invalid session name on line 2.
The second error suggests that the web server is unable to write to
your session savedata folder (C:\php5\savedata). Double check
permissions on that directory, or else change it to somewhere under
the windows temp dir.
