Seems like I read somewhere in the forums that if you list the complete path for your starting file; e.g.,
http://444.docs4you.at/portalnode/index.php
or whatever the file is called, indexing will work for you.
You most likely have indexing locked right now, so you'll have to unlock it. Search the forum for how to do that if you don't know how. Also, make sure your LIMIT_DAYS parameter in config.php is set in a way that will let you re-spider your site now.
Good luck, and let us know how it goes.
