Connecting RubyMine using SqlServer

Hi all,

I am new to the world of Ruby & Rails, currently am using RubyMine for developing webapplication, i am trying to connect to sqlserver for which i have installed this gem 'activerecord-sqlserver-adapter' but when i try scaffold command  [in `require': cannot load such file -- tiny_tds (LoadError)] error message is displayed i have installed tiny_tds but the same message is getting displayed. i have changed the database.yml for sqlserver also but its not working. Before trying with RubyMine i have used Eclipse within which it was working perfectly. Pls guide me with this problem.

Thanks & Regards,
Abhishek T
