Hi, Last week I create an on-grid project in PVsyst and saved it, today I was trying to open it but when I clicked on the Load project button my project does not appear, but when I go to the destination folder where the project is saved in my case C:\Users\Raulc\PVsyst660_Data\Projects, I saw that the project I want to open it is there. Why is this happening and hoe can I solve it? Thnkas in advance for any help. Regards
