if you still have the original sfx/self extracting executable, firstly delete the old mame directory (moving the various folders incl. roms, just leaving the cfg and ini folders and the files in mame directory) then delete any folders in the registery for mame or any entries for mame
Once you'd dane that just unzip or click on the sfx/self extracting executable mame file and tell it to unzip to whereever you want it to unzip to and move back the various mame folders incl. roms to the new location and see if that helps
I think there was an option for the UI within the 'miscellaeneous' tab within the default options thing (though i think that had sommat to do with the new UI rather then enabling the existing UI)
