Hello,
The best solution is of course to update your version of software. However, if that isn't an available option, you could re-capture the image from your page itself using the Screen Capture tools. Only instead of a freehand capture, try a box capture.
The created image should remain the same size and you can either place it over the original objects (if it causes no error in the printing process) or delete the unusual shaped object and replace it.
Hopefully that may work for you.
