Learn SQL Student Database -Part-1

I am working through this studenta database project. The problem I have is that the csv files are not always shown in the project after login. How can I get these files to show in the project file area?

Can you please take a screenshot of the window where you have problems and show it to us? More information would be welcome to give us.

Screen shot file uploaded. As you can see no files showing in the editor. The files appeared last night. But as you can see today nothing showing. Fortunately last night I took a copy which I am using now.

Seems like there is not any answers to how my problem here can be fixed??? I have tried hard reset, soft reset reset to the start of the tutorial from say about 50% completed and still I cannot login. The error of port 5432 just keeps coming up?
