			Table 'cs.cscart_lock_keys' doesn't exist in engine (1932)
			

SHOW CREATE TABLE cscart_lock_keys

Looks like the table didn't update during previous updates. Run the following queries:

CREATE TABLE `cscart_lock_keys` (
  `key_id` varchar(64) NOT NULL,
  `token` varchar(64) NOT NULL,
  `expiry_at` int(11) UNSIGNED NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
ALTER TABLE `cscart_lock_keys`
  ADD PRIMARY KEY (`key_id`);
COMMIT;

#1050 - Table 'cscart_lock_keys' already exists

I just realized that the table referenced in you original post contains a "cs." prefix. If this is how your tables are set up then rename the table cscart_lock_keys to cs.cscart_lock_keys.
