Moving a story file

I can't tell for sure, but looking at the trigger, I am suspicious. Those are not the sort of folder and file name I would expect.  I might be wrong, but if they published the project, then went looking for the pdf, I would expect names like this. Drive letters as high as G: are typically network, or removable drives. Of course, neither of those observations is set in stone, and both could be wrong.

What is pretty immutable is that the "open" trigger points to a file on the disk. It is highly unlikely that that file resides at the same exact spot on your disk as it does on mine. I believe you have to publish the project from the same computer where the trigger was created. Get your hands on the file, create the trigger, and publish it. If you send it to a colleague to publish, they need to edit the trigger to make sure it points to the file on their computer before they publish it.
