How do I install or update the module using Magento Connect?
Go into Magento Connect under *System* > *Magento Connect* > *Magento Connect Manager*,
1- First, you have to uninstall the existing module.
2- Make sure to uncheck the *Put store on the maintenance mode* checkbox. If you don't, and if there are any hiccups with the install, it will take your store down.
3- Now download the package and upload it in the *Direct package file upload* section and click *Upload*.
4- In the console check to see that it went through properly.
