Suddenly My Jetpack Plugin disappear?!

Hello guys,

I was really shocked today to find out that my jetpack has suddenly disappear from my wordpress site. It's not in the dashboard. It was just disappear.

When I try to add new plugin, I found jetpack, but when I try to click "install", it gives error message. "Installation failed, destination folder already exist."

Any recommendation to fix this?

Last time, I remember that I update some plugins 2 days ago, including jetpack. But, I dunno it will come to this. Please, help me guys. Thanks
