I'm not sure I understand how this works, but might it be possible? Actually, how is the encryption done on a regular cart? If we can pool all the known data, we might be able to get it to work. Personally, I don't know anything...but I'm willing to spend time on work arounds once I know how the scheme is set up. -Chris -- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/stella.html Don't post pirate BINs to Stellalist.
