Blogsmu turning wp-admin blank white

I installed the blogsmu theme yesterday unsuccessfully. I upload the blogs_mu and the blogs_mu child into my wpcontent/theme folder but when I activate the child theme it goes white.... everything goes white. The wp-admin, and the web page itself. So i have to go to my cpanel and delete the 2 files so that wpmu resorts back to the default theme so I can actually login to my wp-admin backoffice.
I have no clue what is going on... if I dont have all the plugins necessary installed or what.. I have buddypress installed already.. and i placed the file it has in its plugin folder in my plugins folder...

anyone have any idea what im doing wrong?
