can't get correct page to print

I'm regretting I ever bought the ebook version of this!  I'm trying to print select pages of a workbook using the digital editions.  I will assign a specific page number to print but it prints a different page.  I've tried doing the math to compute the difference between what I want and what I get to find the page I want and it still gives me the wrong thing.  THen I will go back and try the actual page number again only to get yet a different page from the wrong one I got the first time.  I don't have time for this!  I am very frustrated.  Please help!  I tried shutting everything down and restarting with no success.
