Opening PDF's in X3 (Windows 7)

Up until today I've been running CorelDRAW X3 on Windows XP. I was never able to open most PDF files using Corel. I downloaded a PostScript driver years ago (cannot remember where) and so then I would open it in Adobe Reader, Print to PostScript (checking the print to file box), then import that file into Corel.  That worked 95% of the time. Well, we just changed over to Windows 7, and I still cannot open PDF's and I can't seem to find a PostScript driver/printer that will work. Any ideas on how to open PDF's in CorelDRAW X3?
