SharePoint Import file Error

Hi,

We are getting error while importing the files from SharePoint 2007 one server to SharePoint 2007 Other Server.

Have anybody faced this kind of error while importing of the files. The error is as below-

FatalError: There can only be one instance of this list type in a web.An instance already exists.
