RESA Simulator malfunction

Hello, after typing and saving the input for the RESA simulator in a .s file, while using the guide and following every step, i tried opening the .s file using the simulator, and then the software shut down and erased the contents of the .s file.
what can i do to solve this? thank you.

Unfortunately, nothing now.
