Thanks for answering it a lot.The non-cracked SWFs has a protection that checks if the hostname the SWF is hosted on is correct like *.habbo.com - where * would be a subdomain (like images.habbo.com). So in order to get it work on local servers (yes this includes also dedicated, vps' etc.) this protection will need to be removed. I do not know how it's done, but that is the difference.
