I need no paragraphs or spacings in my word 2010.

I have...
1) Changed style --> 2003 --> set as default.
This is gone when I open a new document and I am back with spacing and paragraphs of 2010 version

2) Edited the heading "normal" to be w/o paragraph and spacing. I have pressed OK to "new documents based on this template".
This is gone when I open a new document and I am back with spacing and paragraphs of 2010 version

3) Options --> Advanced --> go to bottom and choose "Lay out this document..." and chosen 2003 instead of 2010
This is gone when I open a new document and I am back with spacing and paragraphs of 2010 version

I don't GET why it won't save my default settings. I want to remove the paragraphs and spacings, but I can't figure out how to effing do this.

I mean, MS Word used to be simple. What the effing happened?

I hope someone can help. I am going crazy.
