Saving external data in base

I have a PC my co-worker has a Mac. She got an MS Access file from another person which she can’t open on her Mac. No, the other person can’t save it some other way for her. I was trying to be nice and save it as an odb file for her but to my surprise, when she opens it, there is no data and it can’t find the “URL”. This is even when I transfer the original access file, too. Really? I JUST WANT GET THE DATA from the Access file to a odb file so she and open and use the information in the database. Is that to much to ask? Can some PLEASE tell me what I’m doing wrong? It honestly shouldn’t be so difficult.

Please take a look into:
