Backward Trajectories

[RPAR]

Hello,
I'm working with HYSPLIT4 and I'm trying to run 2 months of houly trajectories with a total run time of 120h for 1 location, unfortunately, it is not even close to work.

I already downloaded all the meteorological data (GDAS1);
set the setup run (exept the output file, I don't know what to do with that, I tried to set the folder that I want my files to be saved but it don't work);
changed the advanced setup ->trajectory ->menu#3 to 1,120,1;
run model.

I did all of these but it still not working, does anybody know how can I generate the endpoint file (txt) and where it will be saved?
Thanks for the attention, hope someone helps me!!
