astra_lestat, I assume you got the problems with 2.2.1 -- you should have kept 2.1.6, it worked well for most people (some people did have/are having problems with 2.2.1).
If you want, you can try
PDFRead, which is eventually going to be merged as PDFRasterFarian 3. It has a very basic GUI, and should work for most people out-of-the box.
