I have a pre-ordered Poser 5 i didn't load till the latest patch. I installed it, reboot [didn't start it!!!], installed missing morphs, reboot, again no startup, installed SR2.1, reboot, started it, put in my serial and that's it. No call for authorization, nothing. Quite a relief. I wouldn't wait till they rewrite the cds, you may have a damn long wait-- after all, they are still requiring the download patch for Pro Pack. Besides if-- and it's a big if-- they ever go on to another patch that fixes at least some of the memory probs, they won't want to confuse that with a pre-patched P5. I realise this is highly unlikely [some people consider the memory probs unfixable] but I'll bet it's part of their reasoning. Emily
