A couple of weeks ago I installed a program called Sirius Mac, an app to listen to the Sirius Radio stream on your desktop. Despite having come from the apple site, the program didn't work, so I got rid of it. Ever since then my system has been having an issue dealing with pdf's. If I attempt to save as a pdf, from ANY program, it crashes. If I open a pdf with apple preview, it won't print. Anyone have similar issues? Any help is much appreciated.
