I'm guessing you're trying to get the NLA (IVW) in Holland to convert your LPE. If so, they have a court case looming in August for refusing to accept a CAD issued LPE Level 6. You can quote “Besluit Bewijzen van Bevoegdheid voor de Luchtvaart Artikel 8.1.C” to them. It's still valid. You can also (as I am currently doing) transfer your licence to another JAA state, have that state issue your Level 6, and then transfer your licence back to Holland. It's cheaper than taking the course and coughing up the ridiculous dough they want.
