Theme my Login and Polylamg

Hello, i’ve been searching for use of theme my login in different languages. Lots of results, but none effective answer. Would someone please send me a link or whatever info that could help me to figure out how to translate theme my login and use it in a two languages site?

i tried to use this example [theme-my-login register_template=”my-register-form.php”]

and nothing happens!!!

Thank you!

Jeffe
