Recovery Manager for Exchange - Netbackup

Hi I am using a trail version of the RME with Netbackup . I am attempting to restore a Exchange 2003 backup directly from tape and the catalog phase fails with error " next files not found " . I read in the user guide that direct restore doesnt support multiplexed tapes ,so i copied the file to disk using netbackup duplicaiton and have on the images files of the backup that i required. I attempted direct recover again and it complains " that it couldnt find all the files required" it is a full backup images and i can see all the Storage groups in NBU restore console.
