Project configuration error

[Osman doğan]

Hello dear all,

I am Osman, an MSc student and  I am currently working on my QTRANUS project for my MSc dissertation project.

I have created my shapefiles according to the manual.After specifying the project file, zone shapefile, network shapefile, and node shapefile, I tried to save the project configuration. But it gives an error(attached below).

If I dismiss this error and click the data button, I get an error again as shown in the second picture.

Has anyone had this error? I will be appreciated for help 

Kind regards 

Osman
