Cant import saved game

I really love the game, but for some reason I cant import my save file from this game to the next one. I cant recommend this game until my character switches over to the next. I have already searched the Internet and choice of games forum but still have found no solution. I really hope you fix this because as I said, I love the game, but It ruins the experience for me not being able to import my character to the next game, thanks.
