Error loading STAAD analysis data into RCDC "Unable to read analysis data"

When opening a STAAD file in RCDC or trying to open the advanced concrete design module through STAAD, I get the error "Unable to read analysis data". I'm using STAAD CE 22.04.00.40 and RCDC CE 09.02.00.32. I've checked that my loading in STAAD has load types assigned to the basic load cases... it's a very simple single equipment point load on a concrete grade beam. Please advise on what the issue could be. 

The STAAD file is attached.

Thank you,
