Question: Maple doesn't recognize 'complexplot3d'

I'm new here, so I'm not totally sure this is the right place to ask this. I apologize if it isn't, please let me know in that case.

 

My problem is that Maple won't recognize the built-in command 'complexplot3d'. For example, typing:

complexplot3d(z^2, z = -1-I .. 1+I)

doesn't do anything, and it's displayed again in blue as if it was not a command.

 

Any kind of help would be extremely helpful, as I have no clue of what's going on. Thanks in advance!
