Hi all, [bigears]

Aomebody knows what is wrong in the following restart?
The error is the following:

*** USER FATAL MESSAGE 2134 (GP3)
LOAD OR DEFORM SET 1 DEFINED FOR BOTH GRAVITY AND NON-GRAVITY LOADS.
*** USER FATAL MESSAGE 4390 (LCGEN)
LSEQ ENTRY 1 REQUESTED VIA LOADSET DOES NOT EXIST IN THE BULK DATA
*** SYSTEM FATAL MESSAGE 3001 (GP4)

and the .bdf files are:
