Sometimes it takes a bit to get a reply. Please do not use curse words here as this is an all ages, family friendly place.
As far as your quad, have you deleted the Go app and tried re-loading it? Also, please give us as much info as possible like which version P3 you have, what brand memory card and size it is. I assume it was working when you first got it... anything happen? Any crashes?
