hm thats weird did you have the game installed before?
ok like i said i MIGHT be able to help you so apologies if i cant (;′⌒`)
1. when you press the day two button does it take you to this dialogue? 
2. have you tried just progressing through day one to day two or have you just clicked the day 2 button and your having problems?
3. have you tried fully deleting the file?
