#1 error in miki.php require HTML/IT.php

[Sunset]

Hello,
I am trying to install Miki: the database set up fine from
the schema, the .htaccess modifications work, the cron job
is all set up, i've edited main.php ($_SERVER['CREDS', 'DSN'
and 'LANG']), but when I get the errors:

Warning: main(HTML/IT.php): failed to open stream: No
such file or directory in
/home/co-op/public_html/sam/miki/miki.php on line 24

Fatal error: main(): Failed opening required 'HTML/IT.php'
(include_path='.:/usr/lib/php:/usr/local/lib/php') in
/home/co-op/public_html/sam/miki/miki.php on line 24

I have tried changing "HTML/IT.php" to
"HTML/Template/IT.php" (that's the only similar reference
to that sort of thing I could find in the pear docs) but it did
nothing... I don't really know what I'm doing though...

Thanks,
Sam
