Ableton Live Presets folder empty

Missing your default packs/library/presets? Can't repair the Library? Do this:

in regards to missing libraries - go to preferences - this will bring up a page - select change library location (this has to be a valid location on ur pc). then once u have done that select "install library". this will take a while as the library is huge. Once u have done that it will work and u can then select library instruments and they will be there for you. hope this has helped.
