Redmine

I'm Running on a Windows Server.
Redmine V2.3.1
Ruby 1.8.7
MS SQL Server 2008R2
everything seems to be installing OK.
after running rake db:migrate, I ran rake redmine:load_defautl_data
I received the error message:
Error: TinyTds::Error: Invalid column name 'builtin'. EXEC sp_executesql N'SELECT
TOP (1) 1 AS one FROM [roles] WHERE [roles].[builtin] = 0'
default configuration data not loaded.

Help please!
