Media Files 404 Error Multisite

OK so yesterday i made some changes to the .htaccess file as told by a message in wordpress, and tried to make my multisite a single site and failed. Made the changes but the media files stopped showing up. I then reverted back to a 2 day old wp-config.php file and .htaccess as those were the only two i touched.

This should be showing an image but it dosent:
http://syssu.com/files/2010/04/NHL-GameCenter-Live-Home-Screen.jpg

Real upload path as i did some hunting around to find out its:
/wp-content/blogs.dir/1/files/2010/04/NHL-GameCenter-Live-Home-Screen.jpg

BUT when i try to view that file in the browser i get the 404 error yet again. Im not sure if its a permissions issue or a .htaccess file issue but Id like to get it fixed. Here is my .htaccess file for you to take a look at.

RewriteEngine On
RewriteBase /

#uploaded files
RewriteRule ^(.*/)?files/$ index.php [L]
RewriteCond %{REQUEST_URI} !.*wp-content/plugins.*
RewriteRule ^(.*/)?files/(.*) wp-content/blogs.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteCond %{REQUEST_URI} ^.*/wp-admin$
RewriteRule ^(.+)$ $1/ [R=301,L]

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

<IfModule mod_security.c>
<Files async-upload.php>

Thank you in advance!
