Hi - I have exactly the same problem. I have go through a lengthy conversation with support on this trying to get to the bottom of it however they are not responding anymore. I have done the following: Uninstalled and reinstalled twice, second time clearning all legacy files after uninstall. I have checked the firewall application rules - no issue and even then I ensured Poser was given full permissions. Turned off my firewall, antivirus and my routers firewall - no change. I have done a tracert to the server through command prompt - according to support it is getting through so there is no problem with my net connection. Previous Smith Micro version worked fine - contacted server and installed smoothly with no problems.

My machine is running windows 7, all up to date. Not sure what else I can say. I use poser pro all the time and now its an rather expensive error message plus I cannot get my own models out of it.

If anyone has any ideas, I am open to them, but I am at a loss and support is not responding anymore.
