There's far too many choices and variables to allow for skipping content, unfortunately, so no - no way to skip.
Even if your game was deleted, though, re-installing it should give you access to your old saves (they're saved both to your game folder and your local drive) . You can also check your autosaves (click on the "A" next to the page numbers at the bottom of the LOAD screen) if your manual saves have gone screwy.
