There seems to be a very high number of combinations to try, unless the documentation is entirely unambiguous. While you're waiting for a logical solution to your problem from the WA_guys, have you tried this exact combo?
$WAGLOBAL_Root_URL = "http://studio-n.se/cms100/" ; //Absolute path to your site folder.
$WAGLOBAL_Site_Name = "Studio N" ;
$WAGLOBAL_localRoot = "/CMS100/"; //relative path to your PowerCMS files on your local testing server.
$WAGLOBAL_remoteRoot = "/CMS100/"; //relative path to your PowerCMS files on your remote server.
$WAGLOBAL_Images_Folder = "images/";
$WAGLOBAL_Swf_Folder = "swf/";
Just something to do while you're waiting! (Not holding my breath).
