Lagrangian Surface is Empty Error Message in Hypercrash


Hello,
I've been trying to run a fairly basic simulation in HyperCrash using the Radioss solver, however I keep getting an error that shows as:
ERROR ID : 119
** ERROR IN INTERFACE 22 DEFINITION
DESCRIPTION :
-- INTERFACE ID : 1
-- INTERFACE TITLE : New INTER 1
LAGRANGIAN SURFACE IS EMPTY
Additionally, there are a few warnings that show, however I've worked through them before and am less concerned by them. The real problem is the Lagrangian Surface error. I'm fairly certain it's related to the contact surface, however I'm not sure what the problem is. Any ideas on how to fix it, and what the error is related to?
Any help is much appreciated, and the .OUT file is attached if it provides any additional insight.
