BMW E90 2006 CAS Replacement & Programming Issue

Hey Guys.

This is the first time i have had an issue when replacing a NEW Control Unit.

I've got a 2006 E90 which has a CAS-2 installed originally.

I ordered a new replacement CAS to chassis number, which supersedes to CAS-3.
I have installed and set-up ISTA-P session, but basic and programmed numbers keep coming up for manual input.

Anyone had this issue?

I'm thinking the problem lies with the ISTA-P Version not being new enough to recognize the new CAS variant.
