problem with Yet Another Related Posts Plugin

[r2iks]

Hi,

I tried to activate this plugin 'Yet Another Related Posts Plugin' and since then i am not able to access my wp-admin interface,

here is the error that I am seeing,

WordPress database error The used table type doesn't support FULLTEXT indexes for query ALTER TABLE wp_posts ADD FULLTEXT `yarpp_title` ( `post_title`) made by require_once, do_action, call_user_func_array, yarpp_upgrade_check

I logged in thru FTP and checked the plugins folder and I didn't see any folder/files related to thsi plugin.

Could someone guide me what to do.
advanced thanks.
