Hey Vilsenhet, don't know if this will still be helpful but here'swhat i tried, when loading an .out file (or any other result file for that matter) used for calculations other than NMR specifically the program crashes immediatly, i was trying to open an output file for a IR calculation, even if you used a output file to create a new input for a NMR calculation, check to see if your resulting output file has any errors in it or if something seems weird or out of place, but using an output file from a NMR only calculation worked great for me.
