Plugin could not be activated…

Hello, on a localhost installation of wordpress I got an error message as I tried to activate your plugin
“Plugin could not be activated because it triggered a fatal error.
Fatal error: Cannot redeclare hmbkp_init() (previously declared in C:\xampp\htdocs\wordpress\wp-content\plugins\backup-with-restore\backupwordpress.php:156) in C:\xampp\htdocs\wordpress\wp-content\plugins\backupwordpress\backupwordpress.php on line 136″
