Strange stuff here. I have installed the A318/A319, however, none of these a/c comes up as as option from the list of airplanes to chose in P3D. Why?   - I recently upgraded from P3D 4.2 to 4.3 ... Only the "Client."   I have LM 4.3 - Please note, I disabled my AV before installing..I have Windows 10  64bit, and Intel 7700K, and 16Gb of RAM.
