Are there compatability issues with opening former X8 files with 'Artistic Media' in?

Hi,

I am trying to open a CorelDraw file which has a number of Artistic Media lines in which was created in X8. Recently my machine was updated by IT at my office and I'm now using CorelDraw 2018 and as of yet have had no problem opening all my old X8 files. However this particular file will not open and all I get is a "cannot read file." error. The file still opens perfectly fine in X8 on another machine - so hasn't corrupted or such like. 

Any thoughts/ideas? Exporting to .svg and reimporting is not giving the desired result (lots of formatting changes which are timely to deal with).
