Hello PVsyst, I've just recently updated to version 6.41. I'll do a simulation, and export 8760 data like I always use to. The simulation runs and I get the popup saying the file has been created successfully. However, when I go open the file, it's missing all the variables selected. The only thing showing is the header, and the hourly time stamps. All the other columns are empty - not even the header for the variables are shown. Help? Thanks
