SP3 works fine for me, exept the error-message shown in the first posting. But clicking "ok" solves it and the liberary appears how it should (loads very much faster than before - big improvement)

Don't know if it helps to solve the problerm, but it only happens, when the computer is not connected to the internet (I'm working offline almost all the time - have a second PC for internet-activities). When having an internet connection, the error doesn't occure.
I definitifely have no problems with my browser or firewall-settings, it simply depends from being offline/online.

Maybe other users may have an additional problem with their browser or firewall, but I the general-problem seems to be, that Poser8 with SP3 askes for an internet-connection at startup (obviosly it has something to do with content-paradies in my case). If the connection is missing - no matter if it's caused by a fault of the firewall/browser or just being offline intentionally - Poser gives out the error-message.

My OS is WIN-XP/SP3 and IE8 with the latest updates. Oh - and the automatic update-function at startup within Poser is disabled in my settings. So that cannot be the reason either.

Poser still might not be perfect - and never was - but at least I see, someone cares for it and doesn't leave us users alone. Thanks!
