Hi, when i try to create a new ruleset online, i get:

Warning: ac_DataBaseApi::require_once(File/Archive.php) [ac-databaseapi.require-once]: failed to open stream: No such file or directory in /home/www/armycalc.com/httpdocs/lib/dbapi.php on line 874

Fatal error: ac_DataBaseApi::require_once() [function.require]: Failed opening required 'File/Archive.php' (include_path='.:/usr/share/php:/usr/share/pear') in /home/www/armycalc.com/httpdocs/lib/dbapi.php on line 874

Any ideas? I've tried this on Firefox, IE and Chrome.

Sorry for that.
Thanks for reporting.
It should work now.
