N00b having troubles with links...

Hello all!
First a BIG thanks to Rick Ellis for such a great framework.
I am a newbie with codeigniter and somewhat a newbie with php. (Learnt it myself and in a month) I am having a problem with linking pages. I have a global header. Some links are there. My problem is that I can't set it to static pages. I mean if it's on the domain level then ok. But if it's not the links are getting wrong. I tried with setting a base_url in the config.php file and adding url to the helper library. But it doesn't work.

I have the following links: Home (index), Login (/login), Register (/register) and some other...
also on the homepage...it's only showing a 127.0.0.1/login instead of 127.0.0.1/index.php/login. Am i missing something? or being a dumbo?
