I am also having the same problem. The error message reads "game.dat has encountered a problem and needs to close." Tried playing this particular section several times but kept getting the same error message. I see that others have had this problem but I do not see where anyone has come back to reply and/or give a solution.
Love both Magic Farm games and was looking forward to playing the Strawberry quest but have not reached that stage yet. Please give us a solution or do you need other information. If so, let me know. Keep up the fantastic work on the Magic Farm and looking forward to Magic Farm 2 coming out.
