I clicked on the link here in my Account to download Poser 11. I entered the serial number to be able to download the software from Smith Micro. It went well until I was on the registration page of Poser 11. It gives me an error stating the serial number is invalid. I copied /pasted the serial number from my account to a text file, then used that for getting access to the content on Smith Micro. Why doesn't it accept it for registration?
