Language Identifier and routing problem

[eluser]RHS[/eluser]
Hi im using CI 2.0.2, im using Language Identifier to manage languages url like:

http://localhost/project/en/controller/function

But it's not working with my custom routes on routes.php, I used this:

Code:

$route['my_route'] = 'controller/function';

It's working with the default language, but when try to open:

http://localhost/project/en/my_route

Sends me to 404 error. What am I doing wrong, cant find out.

Thank You!

Read the URI Language Identifier wiki regarding routes.
