Lbrary error CI_Driver_Library not found

Hey guys. Im new to CodeIgniter development. So for now im being doing maintainance for a web project using CodeIgniter version 2.1.0. When im try run it into my local computer i found somewhat this kind of error.

PHP Code:

Fatal error: Class 'CI_Driver_Library' not found in C:\xampp\htdocs\aiuoriginal\system\libraries\Cache\Cache.php on line 27 


I do try other nearest version of CI to 2.1.4 but it still happen with same error. I do check the Driver file is extended and it have it because it in library system folder. It kind weird event to me. What possible or any suggestion to counter this kind of error? Many thank for any help from expert.
