Did you have installed it directly or adapted?
I'm asking because IIRC the AS/CB have a different plane folder name....
Installed directly. Ok this is the procedure:
step 1: copy all new meshes from Red_Fox90's folder AMT_Aer.Macchi_C. 202\3do\Plane\MC-202_XII(It) and paste into C202CB\3do\Plane\MC-202XIICB(it) and MC-202XIICB(Multi1). Copy and paste also the new wings. Overwrite if requested.
step 2: go to MC-202XIICB(it) and MC-202XIICB(Multi1) folders and open with your text editor the mesh named
"WingLIn_D0" , then add these lines:
