Newly installed PDFCreator v2.3.2 build 6 doesn't work

I’ve just installed a newly downloaded copy of PDF Creator. When I open a .xps file, the PDF Creator printer is there and after selecting that and printing to file, I get a file that cannot be opened by Acrobat Reader or Libre Office. The former says it is an email or the coding is corrupt. The xps file is 18Mbs, but the file produced by PDF Creator is 60MB.
Any suggestions please ?
