To use an emulator, you would need control of your donation and access the donation checker, to allow you to link a fresh mac that can be used with it. ProStreams is a reseller, so you should work with them to see if they will let you know the donation number. The problem would be that you can't use that MAC that you used with the emulator with other addons, like IPTV Stalker, so you would be changing the MAC anytime you want to try a different client.
