Database Connections

I'm new to Crystal Reports and I'm using Crystal Reports 2016.

For some reason, I can never get the Database Expert / Data / My Connections to give me a list of TABLES once I connect no matter what source I use (SQL or Access usually).

Most recently, I used the Xtreme Access database and all I get once I connect is C:\Users\username123\Desktop\xtreme.mdb and then it always says: Add Command!

Where is my table list?
