Hi David, I have a problem about Trnsys file. While the project i designed works on mu computer, it does not work another computer. It shows that it is not reading the file that i have integrated with type 9 as a problem. When i look inside the file, the file is not empty and the data is present in it. Why might it be giving this issue? Best Regards Saygılarımla; iPhone'umdan gönderildi
