I recently installed LOWI from Orbx. EFB2 keeps giving me the above message. It is clearly installed correctly in P3DV4 and I can see the new scenery in the simulation. It's also listed in the database.
I have the most recent update of efb2 installed and i have rebuild the database on numerous occasions.
Can anyone help?
EDIT - It's all sorted now. I had the database pointing to the incorrect folder.
