It looks to me like you didn’t create the child theme properly.
For example, this stylesheet is empty when it should contain an @import rule that references the same stylesheet in the parent folder…

You may have made other errors, I stopped looking as soon as I found that one, so perhaps the best thing would be to delete that child theme and start again from scratch, making sure that you follow each and every step exactly.
Also, before you start make sure you are using the latest version of the theme → http://para.llel.us/support/groups/razor/forum/topic/latest-version-razor/
