The Smith Micro license server is offline. I don't think Poser 10 requires it, though. Bondware gave a free upgrade to Poser 11.2 from versions of Poser above Poser 10, because those are the ones that stopped working after Smith Micro turned off their license servers.

Not sure about Adobe AIR. I know some people had problems when Adobe pulled the plug on Flash, and Windows auto-removed it. Not sure if that affected Poser 10.
