If you had the computer repaired they may have removed Adobe and as far as I know without it Poser 9 won't work.  If you had Poser Pro 2012 (which is the Pro version of 9) then there is a work around.  I am surprised that Poser 9 has worked this long as Adobe is constantly trying to get itself removed from machines in the name of security.  

Poser 5, 6, 7, 8, Poser Pro 9 (2012), 10 (2014), 11, 12, 13, 14
