Doing a sub theme from Pressa - Issues with CSS

I need to do something very common in Drupal, a sub theme. I followed the corresponding instructions in Drupal and managed to have a sub-theme from Pressa and set it default in appearance menu, with its layout configurations and blocks matching Pressa. The problem is with CSS. For some reason, the style-blue.css file that is in sites /default/files/drupalexp/style-blue.css contains about 15 lines of code and the page looks all broken at visual level, since it does not load this particular stylesheet . When I set Pressa as default theme, it comes out perfect as the demo, and the css file contains a lot of code. What could be happening? Its like its not compiling the LESS correctly from the parent theme. 

I copied the template.php file from Pressa, and renamed all the functions to my theme name (Microclar2). For example function microclar2_preprocess_node(&$variables) .

This is my .info file, copied all except the less includes (to inherit from parent), and then only put custom.less, which i will use to add my own css later:

name = Microclar2
description = "Microclar - tema responsive"
core = 7.x
base theme = pressa
