Priority Club made changes to what points count towards elite qualification on January 1, 2013. I wrote an article about this change back in December. Until the end of 2012, all the points earned from various bonuses and partner activities had continued to count toward the requirement of Gold or Platinum status.
Base points earned from Qualifying Rates paid for hotel stays, points collected from partner transactions, PCR Bonus Points Packages and Meeting Rewards are considered Elite Qualifying Points and counted towards membership elite status.
Priority Club used to count points purchased through their Points & Money reward option towards elite qualification but discontinued it.
Points purchased through Buy Priority Club points used to count towards elite qualification and they still do.
