Downloading from LMS

Hi,

So, let's say an (ex) employee created a Storyline file and published it for the LMS where is now resides. Time has passed and it's been brought to our attention that the course needs a few edits. The source (original, unpublished) files are no where to be found and the ex-employee is unreachable (and would likely be uncooperative if reached!).

Is there a way to download a Storyline file from an LMS in such a way that it can be edited in Storyline and republished to reflect the edits?

Thanks for any help!
