I bought the walnut and orange tree before C3d was ever on the Internet.   I hope they will work in Vue 6 when I get it with the serials I was sent at time when I bought the plants.   They worked ok in Vue 5 INf so I think they should be the same but then again with all the copy protection fears I may be wrong.
 Will have to wait untill I get Vue 6 to see. :)
