Theme My Login plugin

Hi,

I hope a wpmudev hero here can help me with this:

I want to use the Theme My Login plugin so I can use custom login/register etc. pages for my site.
When installed, the TML plugin creates a couple of pages where these login/register/reset etc. forms are being put. The URL's will be: SITE.com/login, .../register, .../logout, .../resetpass etc.
But I want to change these URL's. I've tried adding a few lines I've found on other forums to my functions.php and even a theme-my-login-custom.php, but it just won't work.

Somebody here have any experience with this (and more importantly: a solution)?

Thanks!
