Please try to update your system table and to see if it solves your problem. mysql_upgrade is stored in the "bin" folder under the MySQL server installation path.

To use mysql_upgrade, make sure that the server is running, and then invoke it like this:

shell> mysql_upgrade [options]

After running mysql_upgrade, stop the server and restart it so that it uses any changes that were made to the system tables.
