onlye, it sound if you have a corruption in the file that sneaks past the older version.

Three things, you can try:
  1. Click on the SmartShape and open the Names pop-up; check if there are any weird version details and advise back. This is only a check not a solution.
  2. Download expander.exe (http://archive.xaraxone.com/html/shareware.html) and work on a copy of your file. You need to run it in a CMD window but it is very effective.
  3. Sent a copy to Rob-Xar for repair.

In desperation, you could PM it to me. I have XWDPv12.6.2 (25 Apr 2017) on hand and all version up as well as XDPX.
