redwulf - Poser 11 should work fine. Most people have not upgraded to Poser 12. It's not even available for Mac yet.

However, Poser has a "phone home" function. Smith Micro shut down their Poser authentication server, since they no longer own Poser, so if you haven't installed the Bondware version of Poser 11, you have to do that.

If you have done that...you have to let Poser phone home. Make sure it has access to the Internet.
