It looks like you have FlexSlider and Fomigo Slider installed but Formigo slider appears to be missing from your /packages directory.
This error message is being produced by Formigo Slider, not FlexSlider.
Are you certain you are trying to add the correct slider?
If you have deleted Formigo slider from your packages directory, adding it back should get rid of the error.
If you are wanting to uninstall formigo slider, you do this from the "extend concrete5" page located in the dashboard by clicking on "details" next to the add-on then "uninstall".
Please let us know if this helps.
