OT - Dreamweaver MX help needed

Hi all, Sorry to waste bandwidth with this request. In a moment of madness late last night, I modified my 'MMDocumenttypes.xml' file without taking a backup first. Since then, I get a 'fatal error' message whenever I start DW. I would just re-install from scratch but my CD set is back in Edinburgh and I won't be there until Friday night. Can anyone be a real star and send me a copy? I can be found in the dreamweaver\Configuration\Documenttypes folder. MTIA George in Oxford
