S.Kontogiannis is on a distinguished road

Following a previous thread found in Problem with running tutorial "Constrained Optimal Shape Design of a Fixed Wing" , I experience similar issues in executing the tutorial.
Apparently, in the previous thread the problem was related with geometrical constraints (for example: MAX_THICKNESS_SEC1), and limited to version 4.3.0.
However, I experience the same issue when using version 4.2 and lift as a constraint.
The settings on the cfg file are the tutorial default ones.
% Optimization objective function with scaling factor
% ex= Objective * Scale
% Optimization constraint functions with scaling factors, separated by semicolons
% ex= (Objective = Value ) * Scale, use '>','<','='
OPT_CONSTRAINT= (LIFT > 0.2864) * 0.1; (MAX_THICKNESS_SEC1 > 0.0570) * 0.1; (MAX_THICKNESS_SEC2 > 0.0513) * 0.1; (MAX_THICKNESS_SEC3 > 0.0457) * 0.1; (MAX_THICKNESS_SEC4 > 0.0399) * 0.1; (MAX_THICKNESS_SEC5 > 0.0343) * 0.1

The error I get is:

Traceback (most recent call last):

Thanks everyone for your help!
