Hi, we have an issue with the importation of saved files. working on: tools/monthly meteo computation, we have set some horizon points, properly saved them but as we try to load the file, PVsyst find it, but load a blank graphic. All points are lost. We are a group of students with a proper licenced and activated PVsyst 6.41 versions, few of our classroom's desktops encouter the issue, and have other problem with saves/loads on PVsyst thanks for your help best regards.
