I am trying to produce insar out of 2 different files. i load the data, start Graphs -> InSar Graphs and chose 1st and 2nd file. Then there is this problem with Apply-Orbit-file: No valid orbit file found… There is a URL in the msg from where i can download the file. I did it and put it into the folder that is written in the msg. I restarted the software but the error is present again. What am I doing wrong?
