Updated plugin -> deleted itself

Hi there,

I updated my “Jetpack” plugin and it ended up deleting itself and everything included inside. I had an e-mail list going on and it also managed my comments.

When I tried reinstalling it, this message came up:

Downloading install package from https://downloads.wp.xz.cn/plugin/jetpack.3.0.2.zip…

Unpacking the package…

Installing the plugin…

Destination folder already exists. /home/domain/wp-content/plugins/jetpack/

Plugin install failed.

Is there anything I can do to re-install it with all of my old settings in there? Im assuming its not lost since the destination folder still exists but I have no idea how to find it.

Thank you for reading and I hope this is an easy solution. I am not that computer savvy when it comes to the back-end of websites.
