I'm trying to upgrade my version from 5.6.1.2 to 5.6.2.1 but when I try, It gives me this:

Fatal error: Class Job contains 3 abstract methods and must therefore be declared abstract or implement the remaining methods (Concrete5_Model_Job::run, Concrete5_Model_Job::getJobName, Concrete5_Model_Job::getJobDescription) in /home1/savager2/public_html/savageriver/models/job.php on line 5

Then when I go to the dashboard and try to upgrade through it, It tells me I am running the lastest update 5.6.1.2 and on the bottom of all of my site pages is this error:

Fatal error: Class Job contains 3 abstract methods and must therefore be declared abstract or implement the remaining methods (Concrete5_Model_Job::run, Concrete5_Model_Job::getJobName, Concrete5_Model_Job::getJobDescription) in /home1/savager2/public_html/savageriver/models/job.php on line 5

Does anyone have any idea where I should be looking to fix this?
