Whenever I enter a url which isn't the default, I get redirected to dir above root

[eluser]toopay[/eluser]
how about this....

Code:

RewriteEngine On
RewriteBase /admin/

RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /admin/index.php?/$1 [L]

RewriteCond %{REQUEST_URI} ^application.*
RewriteRule ^(.*)$ /admin/index.php?/$1 [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /admin/index.php?/$1 [L]
