Slightly of topic, but just incase it helps. I had no problems indtaling and runing Poser 6. However it crashed as soon as I tried to assecc any room. I did the re-instal withou firewall and anti-virus. I did my first run without them as well. I accessed the material room without problems. Rebooted. Tried the material room and it worked but none of the other rooms did. What was difrent. I had killed the help that pops up in the material room but not the others. I restarted withou firewal and virus. Killed each rooms popup help and rebooted. Now everyting is fine. Go figure. Hope it helps atleast someone else.
