Hummingbird .htaccess not found

Hi there,

I'm having serious issues with the speed of my site. Some are host related, some are "my first theme" related... To check on that, I have installed Hummingbird a week ago, and now I'm trying to master it.

Hummingbird suggests to add code to my .htaccess file since it cannot do it automatically.
I have a few questions about that.

1. my .htaccess is located in my /wp-content directory. Is that ok?
2. why can't he automatically add the content? Chmod of the file is 644 but even changing it to 777 (temp) doesn't fix it.
3. I can paste it manually but I have to put it after the <directory> element. But there is no <directory> tag in my code?!

Thank you very much for all your help!

Kind regards,

Michaël

The code:

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

# added to make snapshot pro work

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]
