K2 login, not working?

Is the Template working with the K2 login module?

I've tried to change the joomla login to K2 version but i only gets a 404-error page when trying to log in.

Have I missed a update or something? Would love to get it to work.

Edit: I have joomla 2.5.8, template version 2.12 and tried to keep everything else up-to-date.
Edit 2: The problem seems to be something like the template lacking com_users? Thats what I can find out at least.

Did you enable the K2 user profiles in K2 configuration ? Could you switch to default template and test register ? Please check also the reCaptcha configuration.
