When I load my print projects to Acrobat and print from Acrobat, my blacks turn green. WHY!!??!

Question

Sometimes I have to color match at work, or just adjust images in Photoshop CS4.  I save as a Adobe PDF, and load it into Acrobat Pro.
I do not flatten or convert to PDF 1a, just print from Acrobat.  When I print, my blacks in the print are green.  WHY??
