I have exactly the same problem with Bryce 7.1 Pro I have found you can't import pictures in it without the colour being changed and then it crashes (pity Bryce 7.1 Pro has a Great new features but I have reverted back to 6.3 because the program crashes every 5 minutes.

I suggest you make something with a picture in Bryce 6.3 and then try making it a .obp file then import it to bryce 7 pro. another thing you might want to take into account if mac users get this message when Bryce crashs

 

Bad Process

KERN ERROR Invalid address

 

its a lot more said in it than that but what I suggest you do is move everything from the folder you have your work in to another folder and then delete the Old Folder and see if that helps it helped me out a lot.
