I deleted the game and reinstalled it now I have to start the game all over,why?

Solution
It's very likely that your save files were on a local drive, and when you uninstalled the game the process also wipes your save files.

Personally, I put my saves either on a cloud service or put them on a separate drive when I need to uninstall games so I won't lose them.
