MySQL don't start

I recently update my xampp to the latest version, and, MySQL don't start. Here you can see the log error;

Note that I copy the

How did you "update" Xampp? There is neither an update procedure, nor an update installation. If you simply installed a new version over the old, you destroyed all documents and all databases.

This is how I upgarde from 5.5 to 5.6.3 (latest).

1. Rename C:\xampp to C:\xampp_oldbkp
2. Install new version with insatller to C:\xampp
3. Move all the file and folder from C:\xampp_old_bkp\htdocs to C:\xampp\htdocs (works great!)
4. Move all the file and folder from C:\xampp-old_bkp\mysql\data to C:\xampp\mysql\data

This is all my steps and the PHP and APACHE are working great.

EDIT: I reinstall the mysql folder file by deafult and copied only my database. the problem was corrupted file with the older version and new one.

Problem solved! :D

Tank you.
