File .Smash error

Hallo. i have a problem with .smash file. whenever my program crash(not responding) because it use too much ram or something, it need to close program. and after that happen when i open my .smash it didnt automaticly load the data i already saved. i need to import .smash just to get the model back. but all of simulation and analysis is gone

There should be, in the same folder where the smash project is, a file named as the smash file, but starting with a ".", like ".Name_of_the_File.smash.xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx".
Try to drag that file directly into Sim4Life and save it with a different name. From there you should be able to go on with the models/simulations/analysis settings already saved.
