I get this message all the time when I select a part, and try to bring into PE. I unselect everything, select, what I believe to be, a single part, try again, and often get the message again. I there a way to select parts that avoids this? Thanks.
I've notice on occasion that when you select a part, the parts behind it can also get selected. If you can put it at an angle and be sure just the one part is selected you should be able to continue. It this is no the case then you might have a different problem.
