When I upgraded to poser 11 I put in my serial code and it activated just fine WITHOUT issues. I even recently made an image with Lafemme about 2 to 3 days ago.. And now when I try opening it , it says that my grace period expired, my "old serial numbers" are wrong and I can't use the serial number that was recently with my poser 11.. and honestly I don't want to buy it again just to get a new activation code. can someone please assist me? (oh and i'm on windows)
