Wilco A320 No Lights

Just bought the newly released Wilco A320 add-on (by Just Flight) but don't seem to have any external lighting. Switches are definitely on, pressing L doesn't make any difference (hasn't been assigned to something else) and all other default and add-on aircraft I have work okay.
Anyone ideas?
Haven't been able to contact Wilco about it.
