I recommend making a back up before updating and then you can install it over the top of your current installation. After it has installed you will have a new option in the component configuration options under the General tab, select Sharer and save then clear your Joomla cache.
Let me know if you have any follow up questions.
PS. You can always revert to the old version if you have any issues.
