server not starting

Hey guys,

I cant seem to start my rails server anymore. I have been working with
no issue for about a week and then my project has stopped working. I
suspect an issue with the ruby gems system. Here is the stack trace i
get when i try and run script server...

/Users/portablelaptop/Workspace/blueprint/config/environment.rb:45:
You have a nil object when you didn't expect it! (NoMethodError)
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]
