Errors writing to WooCommerce tables

I’m running your plugin on a WP Network that does not have WooCommerce installed. My sysadmin tells me there are a few million errors in his logs that seem to be coming from this plugin trying to SELECT FROM non-existent DB tables used by WooCommerce.

Any chance we can get all the WooCommerce stuff shut off if WooCommerce is not installed? Or, check for DB tables before trying to select?

Love the plugin. Thanks in advance for any help.
