Not sure if your old savegame is still compatible with the last version, but here is how you can get it back :
- Go to "Documents" folder
- Open "Сохранения игр Quest Navigator"
- Inside you'll find one folder with a lot of characters, letters and numbers, and inside that folder, you'll find your savegame, 1.sav, 2.sav, etc.. (6.sav is the autosave)
Now what you need to know is that there's a different folder inside Сохранения игр Quest Navigator for each version of the game (maybe you already have several?). Anyway, you just need to find which folder corresponds to version 46, and which one corresponds to 60FF, so that you just move your old savegame (1.sav if it was saved on the slot #1 and so on) from the folder of old version, to the folder of the new version, then you could just load your old 46 savegame into the 60FF version of the game. I hope I'm clear in my explanations :x
If there's only one folder, launch SOA 60FF, start a new game, and save the game, it will create a folder for version 60FF
