Facebook: unknown error code during application install "-24"

[Gyrobob]

Facebook worked fine for a while, but then kept freezing. So,.. I uninstalled, and tried to reload. That causes: unknown error code during application install "-24"

When I go to data/data there are no facebook entries to delete.

Will I have to do a factory reset? If so,
-- Will I lose anything?,.... apps, data, MMS, SMS, email, etc?
-- What should I back up first?

Except for this issue, the Droid Turbo is fantastic.

Thanks for any help.

Uninstall it again and then reinstall it. It may have been an issue with the play store. Until you can reinstall it just open it in chrome. It looks almost exactly the same.
