Connecting to a Plex Database from Power Pivot in MS Excel

Hello,

Connecting to Plex or even using the tables is completely new to me.  I'm a SQL novice, but pick up on things quickly. 

I'm trying to connect Power Pivot in MS Excel to Plex like I have been able to do for MS Access databases.  However, I'm receiving the error below:

I'm able to actually connect to Plex, because you can see above that I'm pulling in what looks like 6,397 tables.  The problem is that I'm not getting any columns.  There should be a preview of the table where the error message is showing.  Below is the Advanced Editor statement and what I see in the Query editor:

Any help would be greatly appreciated even if it is just assumptions or guesses that might lead me in the correct direction.

My understanding is that nobody else is using MS PowerPivot or MS PowerQuery to connect to Plex.

Thanks,

James
