Plugin is not activating

Hi there,

I’ve been using the plugin for a while and it worked smoothly. I deactivated a few days ago to debug an issue and when I tried to reactivated it again this fatal error came up:

Plugin could not be activated because it triggered a fatal error.
Fatal error: Uncaught TypeError: Argument 1 passed to mailchimp_as_push() must be an instance of Mailchimp_Woocommerce_Job, instance of __PHP_Incomplete_Class given, called in /homepages/20/d772643783/htdocs/clickandbuilds/TasteBack/wp-content/plugins/mailchimp-for-woocommerce/includes/class-mailchimp-woocommerce-activator.php on line 113 and defined in /homepages/20/d772643783/htdocs/clickandbuilds/TasteBack/wp-content/plugins/mailchimp-for-woocommerce/bootstrap.php:106 Stack trace: #0 /homepages/20/d772643783/htdocs/clickandbuilds/TasteBack/wp-content/plugins/mailchimp-for-woocommerce/includes/class-mailchimp-woocommerce-activator.php(113): mailchimp_as_push(Object(__PHP_Incomplete_Class), 90) #1 /homepages/20/d772643783/htdocs/clickandbuilds/TasteBack/wp-content/plugins/mailchimp-for-woocommerce/includes/class-mailchimp-woocommerce-activator.php(27): MailChimp_WooCommerce_Activator::migrate_jobs() #2 /homepages/20/d772643783/htdocs/clickandbuilds/TasteBack/wp-content/plugins/mailchimp-for-woocommerce/bootstrap.php(533) in /homepages/20/d772643783/htdocs/clickandbuilds/TasteBack/wp-content/plugins/mailchimp-for-woocommerce/bootstrap.php on line 106

I’ve tried different things but I couldn’t make it work again. Do you have any ideas what can I do to make it work? I’m desperate so any help would be very much appreciated.

Thanks a lot!
