Is the text machine translated to English from some other language? I find the text quite hard to understand.
I’m just guessing you downloaded the new version of game and want to know how to continue from the save made in previous version? If so, you should say what platform you are using and what is the old version and new. I play on Linux, and unpacked the new version to new folder, then copied save files from game/saves from old directory to new to the same place.
