Marketpress installation struggle

Hi there!

To start with, can't wait to go to bed and wake up tomorrow.
cause it has been a long long long day and journey.
I'm a beginner and just joined you guys this morning,
so I'm ready to read and learn everything you will through at me.
If you do :wink:.
I bought marketpress this morning after a week of research... And the installation is a nightmare, it has been asking me for a style.css stylesheet file (cause empty) to start with,
now I am in... think so... can't read anything since I installed WPMU DEV dasboard, it doesn't seem to be compatible with my wordpress the window is a mess. And so much more but really too tired and frustrated so I will bother you with my silly questions tomorrow... if I wake up.
