Arbortext Editor/Architect evaluation license

I had an evaluation copy of Editor and Architect (along with a lot of other editors) a few years ago at the start of my PhD research on the usability of XML editors. I now need to run my test harness on the same set of software as a final update, to ensure I am not misrepresenting any product, but I am unable to download a second evaluation copy (error message says "You have entered an invalid product code" although there was nowhere to enter any code). It advises me to use www.ptc.com/olm/contacts.htm but all the phone numbers given for non-US users (me) are the same number (!) and all of them are unobtainable because they are 0-800 numbers which cannot be dialled from another country (and my local one for Ireland is invalid). I managed to get a number for the Munich support centre, but they are either permanently busy or the ringing times out. Is there an email address I can contact someone in PTC on for this enquiry?
