Commodity Trading not activated yet

Hi Team leader!
I am here in Angel One for the last 2 months. I have a problem and I raised many times my problem but no solution is given yet.
When I try to trade Crudeoil or Natural gas, then my order is rejected and a pop up message appears as ’ Client Code A53813123 is not Registered '.
Please solve my problem.

Bro is it solved or still it shows the same error?

I activated them. Still there’s problem
