CRM 4 importing rdl error Root element is missing

When Importing my rdl file from a SSRS project into the C开发者_如何学CRM 4 reports area, I get this error.

Root element is missing

How can I handle that?

@niktrs, thanks but the problem was different.

Actually just figured out that the file that I downloaded on the server from Outlook Web Access Email was empty. checked with notepad.

I copied the contents from the local file into that empty file and saved as the same file with UTF-8 format.

It imports fine without trouble, obviously!
