Bonjour à tous,  
J’ai téléchargé “negative Lab Pro” pour essai il y a quelques mois. j’ai  
voulu l’ouvrir il y a quelques jours et rien ne se passe pourtant je n’ai pas utilisé la possibilité des 12 photographies. Y a t’il une butée calendaire pour l’utilisation gratuite de “negative Lab Pro” ?  
Merci par avance pour vos réponses.  
Bien cordialement.

Translation:  
Hello everyone,  
A few months ago I downloaded “negative Lab Pro” to try. I wanted to open it a few days ago and nothing happens, however I did not use the 12 possible photographs. Is there a time limit for the free use of “negative Lab Pro”?  
Thank you in advance for your answers.  
Best regards.
