Problem with Session tables

What would that be i still can't figure that out.

application/config/libraries directory is empty, only file is index.html.

system/libraries/session/Session.php file exists, that file is capitalized. In the same directory is also session_driver.php and SessionHandlerInterface.php.

I keep getting the same error. I made sure the upgrade to 3.0.1 was done successfully by completely download the new version then adding selected directories and files from the old version to the new version. I copied and pasted the views, controllers, and public folders from the old site. For config files i just re-entered information directly into the new config files instead of copying the old config files which i understand are outdated.

Upon autoloading 'session', why would I get an error in SQL syntax, while it also appears its trying to insert data into the old version of ci_sessions table??

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SET `last_activity` = 1442496306, `user_data` = 'a:3:{s:9:\"user_data\";s:0:\"\"' at line 1

UPDATE SET `last_activity` = 1442496306, `user_data` = 'a:3:{s:9:\"user_data\";s:0:\"\";s:7:\"user_id\";s:1:\"1\";s:6:\"f_name\";s:5:\"Geoff\";}' WHERE `session_id` = '47511770dba0f8e475664805ef4fe9a0'
