Akismet Plugin Error

Hi To everyone..

I Am using akismet plugin as everyone 🙂

I have installed it to /wp-content/plugins/akismet folder … but now i want to change its place as /wp-content/plugins folder and delete gif file.. I have deleted gif file and edited background url: from css options in akismet.php.. but it was given error…

I think it’s releated to my database that akismet must be in plugins/akismet folder.. If it is like that I think that deleting this line from phpmyadmin will solve.. where I can delete this line in database??
