Unfortunately the latest version of Poser uses an updated Python engine, and as a result compiled Python scripts (.pyc) aren’t running, with the Magic Number error. With luck all that’s needed is a recompile from the original script, though I believe some scripts need more work than that; in any event if you’ve only just purchased and downloaded that obviously isn’t yet done. I would suggest opening a support ticket, asking if there’s a status update, and if need be asking for a refund.
Thank you very much for the message, how would I recompile the scripts to fix the error ? Yes i purchased it two days ago and downloaded it, how would i open a support ticket ?
