[Plugin: WP Super Cache] How to uninstall WP Super Cashe

I try to delete WP Super Cashe and I get the following messages, what or how can uninstall and delete it completely?

Warning: include(../../../wp-load.php) [function.include]: failed to open stream: No such file or directory in /home/emarrufo/public_html/homeslocally.com/wp-content/plugins/wp-super-cache/uninstall.php on line 8

Warning: include(../../../wp-load.php) [function.include]: failed to open stream: No such file or directory in /home/emarrufo/public_html/homeslocally.com/wp-content/plugins/wp-super-cache/uninstall.php on line 8

Warning: include() [function.include]: Failed opening ‘../../../wp-load.php’ for inclusion (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/emarrufo/public_html/homeslocally.com/wp-content/plugins/wp-super-cache/uninstall.php on line 8

UNINSTALL_WPSUPERCACHE must be set to a non-blank value in uninstall.php

Thanks for your help,
