Quote - Bobby, have you tried downloading the prog again?........it'll come with a new code, and it's free.
Just don't trash your old one, any presets you have saved can be incorporated into the new file set.

I just checked the Bryce 5.5 download site and it had this text to it.

"You'll have to register your copy of Bryce on the publishers web-site to gain access to your free Bryce serial number."

So maybe Bobby needs to look at Daz site and serials available to him?
