.htaccess Question...

[devanium]

This is probably a stupid question, but my current root directory .htaccess file looks like this:

-------------------------------------

Options All -Indexes
#ErrorDocument 404 /index.php?error
ErrorDocument 404 /404.php

RewriteEngine On

RewriteRule ^category/([0-9]+).html/?$ index.php?category=$1 [L]
RewriteRule ^news/([0-9]+).html/?$ index.php?news=$1 [L]
RewriteRule ^print/([0-9]+).html/?$ print_version.php?id=$1 [L]
RewriteRule ^pdf/([0-9]+).html/?$ pdf_version.php?id=$1 [L]
RewriteRule ^comments/([0-9]+).html/?$ index.php?comments=$1 [L]
RewriteRule ^author/([^<]+).html/?$ index.php?author=$1 [L]

RewriteRule ^([^.]+)/?$ index.php?category_name=$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^<]+)/([^<]+).html/?$ index.php?news=$2 [L]

-------------------------------------

Now, I just installed a new script (phpadsnew), and it's giving me a 404 error. How can I modify the .htaccess to allow access to this new script?

Any help would be greatly appreciated! Thanks!
