(Have you read Alisa's letter yet on your phone?)
These are all the clickable places I could go, I thought of sending this, maybe it can help. :D If it's still not works, then I can either screen this and send it to the dc server if you are not in, so maybe others can suggest something or you can still delete and re-download the game? I usually just skip to choices when it comes to that so I don't have to replay it entirely :D
