i think at one point i discovered this was a problem with RMS. are you on your own RMS or are you using the freeloaders version? also, just as mentioned above, you have to edit settings in three different places, first and most important is the php.ini secondly is the sites advanced settings, thirdly is the settings in ray itself. get us what you have for your time out sessions and max_upload. then we would like to see where you are connecting to RMS

later,
