I have done the TS Searching job, and found the transition state, I started TS Confirmation job, then met this error: “Error in parameters file: problems parsing file for keyword TSSEARCH_METHOD”. Not sure what is the reason?

the error message is: 

License checkout of MS_castep successful

Error in parameters file: problems parsing file for keyword TSSEARCH_METHOD
Abort(1) on node 0 (rank 0 in comm 0): application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0

Appreciate any help to solve this.
