Update .htaccess

I wanted to change my permalinks so they’re displayed like this: blabla.com/year/month/date/post-name. However, when my precious blog told me to update my .htaccess-file which was when I discovered that I had no .htaccess-file, which was the reason I created one.

I did everything that I could find. I pasted this:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /english/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /english/index.php [L]
</IfModule>

in my texteditor, saved it as .htaccess and uploaded in the wordpress rootfolder ith my FTP client (SmartFTP). But still it’s not working. Is it me who has screwed something up, or is it my blog that’s screwing me up?
