Empty Website Data Source windown


Hi all,

I am Visual Web Developer user and facing a problem when I am creating a local report (.rdlc) file.

I am using Business objects as the Data Source for this report. It was working perfectly until all the items in the Website Data Source window suddenly "disappeared". The "Add New Data Source" button on this window is also disabled. Now the window is just like a blank box only. And I can't continue working with the report file like this...

I have tried undoing what I did before but it does not help at all...

Any reason for this to happen? There is no sign or something at least indicating what is wrong.

Please help.
