Renesas Flash Programmer script execution fail

I tried to write a script for programming a RL78 board using Renesas flash Programmer script as given in Renesas Flash Programmer's User manual chapter 9. But I'm getting an Error(E1010017) : Invalid parameter.

Does any one know this, my script is 

log "d:\Flash Programmer\QB_test\log.txt"
workspace "d:\Flash Programmer\QB_test\QB_test.rws"
script d:\Flash Programmer\QB_test\QB_test\serial_rl78g13_adf7021n_collector_n2.hex
erase

Thanks in advance.
