I can't get my script to work

I'm trying to use dex-explorer script because I've found a way to backdoor HD and give myself owner rank if I can use it

My friend tested this out and it worked, he said it crashed a lot though

But for me everytime I execute the dex-explorer script I crash, I tried to use it about 15 times before heading to the forums for help

(For those of you who want to know how to backdoor HD, you basically just execute dex explorer, look for the owner rank script in HD, and drag it onto your character, then you'll have owner rank)
