APPCRASH/iexplore.exe

I recently did a system restore on my dell 537 and I used to run IE7.  Since the restore, IE9 is what is running now.  When my mother tries to play most of her online games at Pogo.com this is the message that keeps popping up. Never had this problem before. Can someone please help? I did try and go back to IE8 and still the same problem.
