Some TinyMCE plugins wont work

Advanced image and inline popups plugins won't work. Could someone please help me diagnose the cause? plugins part of tinyMCE.init looks ok:

tinyMCE.init({
    mode : "none",
    theme : "advanced",
    relative_urls : false,
    document_base_url : "/",
    language : "en",
    safari_warning : false,
    entity_encoding : "raw",
    verify_html : true,
    preformatted : false,
    convert_fonts_to_styles : true,
    plugins : "advhr,advimage,advlink,autosave,contextmenu,directionality,emotions,flash,fullscreen,iespell,inlinepopups,insertdatetime,layer,paste,preview,print,searchreplace,style,table,zoom",
    theme_advanced_toolbar_location : "bottom",
    theme_advanced_toolbar_align : "center",
    theme_advanced_path_location : "bottom",
    theme_advanced_resizing : true,
    theme_advanced_blockformats : "p,address,pre,h1,h2,h3,h4,h5,h6",
    theme_advanced_buttons3 : "advhr,cut,copy,paste,visualaid,removeformat,charmap,help,ltr,rtl,emotions,flash,fullscreen,iespell,insertlayer,moveforward,movebackward,absolute,pastetext,pasteword,selectall,print,styleprops,tablecontrols",
    theme_advanced_buttons1 : "bold,italic,underline,strikethrough,justifyleft,justifycenter,justifyright,justifyfull,bullist,numlist,outdent,indent,undo,redo,link,unlink,anchor,formatselect,fontselect,fontsizeselect,styleselect",
    theme_advanced_buttons2 : "image,cleanup,forecolor,backcolor,sup,sub,code,hr,insertdate,inserttime,preview,search,replace,zoom",
    extended_valid_elements : "hr[class|width|size|noshade],img[class|src|alt|title|hspace|vspace|width|height|align|onmouseover|onmouseout|name],a[name|href|target|title|onclick],img[class|src|alt|title|hspace|vspace|width|height|align|onmouseover|onmouseout|name|obj|param|embed]",
    plugin_insertdate_dateFormat : "%Y-%m-%d",
    plugin_insertdate_timeFormat : "%H:%M:%S",
    content_css : "/themes/mytheme/style.css",
    elements : "edit-body"
  });

editor shows up as it should but when i click the image icon to insert new image i gen the basic inset image dialog. also there is no inline popup option nowhere. i also installed imce module to upload image files but this module also does not work - there is no 'browse' icon when i want to insert new image.
i've downloaded latest version of the module and the editor itself from http://tinymce.moxiecode.com/ and even reinstalled the whole module but without luck. i can't make advimage and inline popups plugins to work and have totally no idea why. i've tried various configurations for the editor - iv enabled and disabled options to see if it helps i've even changed my drupal theme to see if maybe my custom theme messes something up, but these plugins still won't work.
