Unable to edit older images from corel draw in X7

Ok, I do not know all the technical terms but I will do my best to explain my issue.  I have a Microsoft word document with images inserted into it.  The images were created in an earlier version of CorelDraw but I do not know what version.  When a co-worker, who has CorelDraw X4, right mouse clicks on the image it is recognized as a CorelDraw X4 object and he is able to paste it into CorelDraw and edit the image.  Now I have CorelDraw X7 but when I do the same right mouse click the image come up as an unknown object and I am not able to edit it in CorelDraw.

Anyone have any ideas on what is causing this?
