In that case you can try the manual way - if you're using Joomla 1.5 the base URL for articles is "index.php?option=com_content&catid=??&id=??&view=article&Itemid=??"
for Joomla 1.0.x it is "index.php?option=com_content&id=??&task=view&Itemid=??".
You can find the "catid" parameter in Category Manager, the "id" parameter in Article Manager and the "Itemid" parameter in Menu Manager, if the article is linked from menu, otherwise remove the Itemid parameter from URL.
This non-SEF URL should be rewritten automatically by Joomla to its SEF form.
