WooCommerce Plugin Failed to install and is now no longer present

Hi,

I just updated the plugin for WooCommerce to fix the all orders bug, something went wrong and now I’m in a littler bit of bother and not sure of the best way to proceed for fear of overwriting the database / existing orders etc.

I was unable to log into the dashboard but changing the URL has allowed me in, which is great – I’m faced this this message:

Could not find a WooCommerce Install. Facebook for WooCommerce plugin requires WooCommerce v2.6 or higher.
Plugins Add New
Install the WooThemes Updater plugin to get updates for your WooThemes plugins.
Trustpilot plugin requires WooCommerce to be installed and active. Please add Woocommerce plugin to your WordPress page under Plugins section. After installaing and activating plugin you will be able to activate Trustpilot plugin also.
Woo Store Vacation is enabled but not effective. It requires WooCommerce in order to work.

The Affiliates WooCommerce Integration Light plugin requires the WooCommerce plugin to be activated.
WooCommerce Gateway PayPal Checkout requires WooCommerce to be activated
Dismiss this notice.
Stripe requires WooCommerce to be installed and active. You can download WooCommerce here.
YITH Pre Order for WooCommerce is enabled but not effective. It requires WooCommerce in order to work.

Which looks like the WooCommerce element cannot be found or is seriously screwed.

I’m not sure how to rollback without causing further damage.

I’m hosting the site on an AWS box and can ssh in, I’ve not restarted / rebooted the system yet and I don’t have FTP access.

Any help would be hugely appreciated, thank you!
