pdf issue

Hi,

I'm a massive fan of Cycle Travel and thought I'd try out the download pdf function for the first time, but unfortunately it doesn't seem to be working for me. 

When I click the pdf button I get the "Please wait while your pdf is prepared" message then after a few seconds another message pops up at the top which says: "Sorry, a technical fault prevented the PDF from being downloaded. Status: failed". I've tried different scales and different web browsers and switching my PC off and on! It did work once when I tried to download a cue sheet, but now that doesn't seem to work either.

I just wondered if you had any idea what the problem might be?
