FM11 crashing when I import files

Hi,

I'm trying to import an image into FM11 which is in pdf format. I get as far as Import - File - Select File, before FM crashes. Every single time. I've tried importing other pdf files, and FM still crashes. However, when I import 'normal' images files - .tifs or .jpegs, I don't have the same problem. I really need to be able to import the pdfs though. What should I do in this case?

Thanks
