I do have a small wireless network with 2 laptops hooked up to them, but nothing has changed. Same equipment, computers etc. As for my hardware and software setup: Windows XP pro, p4 3.2, Gigabyte 8IK1100, 2 gigs of ram, Radeon x800, Norton internet security and anti-virus. You mentioned a printer being the culprit in your case, I have a HP psc 2410 that is still connected. Many things have changed since i last used poser. I have switched internet providers from SBC DSL to Comcast, but my computer wouldnt know that because of our Netgear firewall router. I did install the comcast software but promptly removed it because it had spyware with it. The reason we switched ISPs was because my GF and I recently moved. I dont see how that would make a difference to poser though. I also finally decided to take the plunge and download SP2. I held out for a while but i figured by now it must be safe. I have already tried uninstalling it to see if poser would work then , but to no effect. I have all the latest versions or updates on my software and drivers, and run a clean system normally. I am constantly screening for spyware and viruses, and run only the programs i need. I am not one of those people with like 20 icons in the bottom right of their taskbar. I have 3 at start-up. The fact that I can't get Poser to run on such a clean system drives me crazy.
