The lab bench is in one of the corners of the room in Leonardo's study.

dear MaG,i am now in the workshop,behind the door,playing the
red yellow ball puzzle,this is too much for me,its a tough
puzzle,therfore the only help,wich you can do for me is,if you have a save game,till after the puzzle.
i thank in advance.
samuel

My saves are not labeled.
I will send you several midway in the game.

dear MaG,all save games,wich you sent me,are no good,all of them,are for day 4,where i am still in middle day 3,you sent me,from save 98,to save 108,and i need between 90,98,little
before wich you sent me,so if you still have,from before,that
might work,please send me.
i thank in advance.
samuel

They are on the way.

dear MaG,it is still no good,the save games,from 90-98,wich
you sent me is still far away from day 3,all are day 4,so lets figure out,my last save is before the ball puzzle,its
number is,14,wich means up to the puzzle i have only 14,saves
and by you,as i see,it goes up into over hundred saves,the major problem is,that they are not labled,to make things short,if from save 90,is still day 4,PLEASE send me from save
75-89,i still must try again.
i thank you a million times,i also feel sorry for all this
samuel

I sent you 60-89. Hope that gets you going, At least you have saves for day 4 already.
