[Help] Correct way editing .crowsale files in EP7

[someD]

I want to change items sold in the NPC example in inven1_0_1.crowsale but every time i logged in game to see if the items change OMG the tab is missing

heres the things i tried

Scenario.

1. I drag inven1_0_1 in a folder drag it again in Ep7 Reditor insert item then drag it to glogic put
it in client and server files. *FAIL*

2. I drag inven1_0_1 in a folder drag it again in Ep7 Reditor select all copy then paste it in
Reditor save it as inven1_0_1 then insert item then drag to glogic same process i just save it
again via Reditor but again *FAIL* tab missing

3. Same process but in the end before i drag it to glogic i encrypt it first, same result tab
missing.

*BUMP*

Am i missing something here? or im doing it the wrong way?

TIA
