NWN ee : Can't transfert save file from pc to android

Hi and happy ne year,

I both own pc and android version of nwn ee, hoping this way to be able to shift at demand in between my pc and smartphone. I am able to copy and play my save files from android to pc without any problem, but not the other way around. In android, when i try to load a save file previously saved in pc, i got the following error
"The module was created with an updated version of nwn"

Any help would be appreciated.
