Classic British Flight Sim

Does anyone know if there is a way to read the AFCAD file from encrypted airports into LNM? I get that LNM can't open the encrypted file, but has anyone come across a way to read in the AFCAD file? (or does anyone have the undecrypted versions of the files for EGHT, EGAA and / or EGPH)

Maybe a slightly different version of the question…
Does anyone have EGNT, EGPH, or EGAA bought through the ORBX installer program? If so, do you know if the scenery stays installed even if the ORBX installer app is removed?
