Thanks again for everyones help. Here is what she did so far and what happens... that might explain things a bit more... i hope :)

 

She has installed the latest Flash for I.E and has the latest version of I.E too (version 8)....everything is updated. She even disabled Firefox so only I.E was the browser for the internet. Poser is going through the firewall no problem...and her art computer can access the local network.

The problem is, when she is in Poser 9, when she wantss to load the library, she has a message saying that Poser needs Flash....there is a link to download it from the Adobe Flash website. She does that (with IE) and when it is time to install the Flash exe, the installation fails….
