Hello!
There is a problem or error about the Vaisala meteo data cannot be input PVsyst. As usual I select the 'Known format' button - 'Vaisala (Worldwide)', then I choose the Vaisala meteo data I have already got, the screen shows' Reading he files', but after a second the screen shows nothing, and I am sure that the data and format are correct. In another case, the same file was correctly identified and input a few days ago. I've tried it on different computers and can't imput the meteo data.
