Bought them from where?
PM has been dead for well over a decade.
From Insight. The license and serials were sent from Adobe.
Get a refund. Pagemaker is way too old and obsolete, it will not run reliably on modern operating systems. Adobe should have stopped selling it about a decade ago, I think they have only recently pulled it from sales. You can get far more productivity from Indesign, or cheaper products like serif page plus, or the free Scribus.
