you also need the txt2gam exe and from qspeditor export to txt2gam
i only did this once so i am not the best but you can try
open qsptools , go to file translator
parser -> qsp , browse and select the previous exported txt file
then you choose yandex or google (you can try both to see which one gives you best result) , also you can try yandex 1.5 but you must have yandex account and an id for translation etc
then translation and you wait
when it finishes press save to save the xml for future
and then open an new qspeditor window import the txt to qspeditor and compare the old qsp and the new one (go to utilities -> game info to see first if locations are the same)
