I've just discovered the G.E.C.K and i follow the tutorial to create new .esp (we can find it tuto on the GECK website).

I'd like to explain my trouble.
I created a new .esp called "Vault74b.esp", i've built some cells and saved it.
After that, I runned the Fallout 3 launcher and chosed "Data files" to check my plug in.
But when I started the game and I typed "COC Vault74" inside the console, nothing happened.
I've a COCMarkerHeading placed in G.E.C.K. on Vault74b.esp, I've Vault74b.esp Setted and I followed all steps.
Maybe I did something wrong when I launch my plugin in G.E.C.K, or maybe I must check fallout3.esp too etc...I don't know how to do.
Someone have an idea?
It's very annoying because I can't check my "creations".
Thank you!
