pm_email_notify settings are missing

I have run update.php. The error message appears on a white page whe I try to access config/messaging/privatemsg/notify

The file pm_email_notify.admin.inc was missing, so I copyed it from the beta folder ("privatemsg_alt") and deleted the beta folder then. Now it works. But now I get this message on the user page (?q=user):

Warning: include_once(/var/www/vhosts/mysite.com/subdomains/test/httpdocs/sites/all/modules/privatemsg_alt/privatemsg.theme.inc) [function.include-once]: failed to open stream: No such file or directory in theme() (Zeile 794 von /var/www/vhosts/mysite.com/subdomains/test/httpdocs/includes/theme.inc).

Furthermore I get this message in config/messaging/privatemsg/filter

Notice: Undefined index: privatemsg_filter_admin in drupal_retrieve_form() (Zeile 736 von /var/www/vhosts/petersitzer.de/subdomains/test/httpdocs/includes/form.inc).

Okay. That works. But i cannot find the settings for email notification. I think I should find them below the tab Deleted messages. The module Privatemsg Email Notification is activated. When I try to disable the module Privatemsg Email Notification I get this error message:

After updating to the latest dev (2011-Jan-12) the error message doesn't appear anymore. So far so good. But I still can't find the the settings for email notification.

Now it works well. Thousand thanks for this great module and support!
