I'm not sure this is the case here, if it were MD would have probably mentioned this 'till now, but I'll go ahead and say it anyway, maybe it helps: as far I know the hot spot is one of a kind regarding that the Site URL form is to be filled in cutting the pagename.html at the end. meaning that instead of
http://www.domain.com/site/1/index.html you need to type
http://www.domain.com/site/1/
