Re-attaching detached project not successful in CS4


I recently detached a project to physically move it. But then when I issued it to be re-attached, the attachment was not successful, now leaving me the only option to delete the project. It still shows as detached.
Appreciate your help.

Thanks, Oliver


Can you please paste the text of any error messages you receive during the detach/attach process, along with any screenshots of the interface indicating the status of the project?
