No Taxi & landing lights for Aerosoft A318/319.

I got no external lights in Aerosoft's A318 / 319. Reloaded the module still no lights. I toggle the taxi and landing light switches but nothing happens. What am I doing wrong? Appreciate your help.

Solved: This is how. Recently I had "out of memory" issues with FSX so I reduced some of the FSX settings. In my wisdom, I turned off the setting "Advanced animations" under the Display - Graphics -Global options. This was the culprit. For some strange reason only the Aerosoft A320 was affected. All the other aircraft had lights.
