AND How to resolve this problem is:
Go to xampp/mysql directory
Rename the /data folder to /data_old
Copy the /backup folder and paste in same place
Rename the /backup_copy folder to /data
Go to /data_old folder and copy all your database folder expect phpmyadmin, mysql, performance_schema
Go to /data folder and paste all database folder copied from /data_old
Go to /data_old folder again and copy ibdata1 file
Go to /data folder again and paste ibdata1 file here
Restart MySQL button server again. twice in my case to make it work.
