Unable to load assembly System.data
===

I tried Red Gate's Net Reflector but it has created more problems for me.  I was debugging System.Data and now when I open my my SQL Server Management Studio, it does not connect to any server because of following error. Any way I can solve it? Red Gate probably will take a very long time to my question as I was using their trial version. Hope someone here can help me.
