I might have one, hold on
EDIT 1: I've got RW 054 and RW Mk1a (the 1a seems to be a later version). What happened was I got a free code during the trail for 054. Then they closed it and made you register after that (but my code still worked). So I have a code for 054 somewhere (I think) but I don't think Mk1a needs a code at all (it just runs as-is).
EDIT 2: Well it seems I lost the code. I just kept it in an e-mail, but I've not used RW in about 4 years, if not more. I'll try Mk1a, install it and see if it asks me for a code or not.
EDIT 3: well Mk1a wants a code. You can't click "get free license" but you CAN go to the RW homepage and get one from there, I believe.
EDIT 4: I uninstalled Mk1a and put 054 on... And.. it didn't say it was a demo, and it didn't say it was limitd to 15 minutes, and it doesn't even have an OPTION to put in the registration code.
You interested?
