onlye, you have typed in some confusion so I apologise if I have the wrong end of things.
There is no such thing as Web Designer Pro 15. Are you referring to Xara Web Designer Premium (XWDP) or Xara Designer Pro X (XDPX)?
My assumption is you used XWDPv15 and your version of XDPX is an earlier one.
If your XDPX is earlier then the SmartShape code might not exist and so you will get a "dead" SmartShape and the complaint.
What is the SmartShape you used?
