Permalinks

Hi everyone. I have posted on this before and figured it out, but somehow I screwed up my permalinks when I switched computers and forget how to get them to work.

I want them to look as such: /archives/%day%/%postname%/

So I did that in the Option>Permalinks area. Then I recreated the .htaccess file and pasted the below code into it. Any thoughts as to what I am doing wrong? When I click on a permalink, I get an error message. Thanks!
