Error opening folder in CDT 4.0.x C++ Project

I just loaded the CDT (4.0.3) into Jazz successfully, and then imported an existing C++ project into my workspace (successfully again). Now when I go to the C++ Project view and try to navigate through my project, there is a single folder (always the same one) that gives me an error when I try to open it: "URI scheme is not 'file'" is the error that is produced. The result is the folder does not open, and subsequently any attempts to open the folder show it devoid of files. This problem does not exist with this project in Eclipse 3.3.x, and indeed does not exist for any of the other folders in this project, or any other project I have thusfar imported into my Jazz workspace.

Any thoughts?

Thanks,
Chris
