UNABLE TO DEL FILES

Hi Pals,

             There is an issue in enterprise pdm like I am the PDM admin and there r some files though i login in as admin

  1.am unable to delete those files .

  2.The files which i have deleted and destroyed still the message pops up like files dont have a unique name.

In 2009 i had put an assembly containig 150 odd files .For some reason i had done 'pack and go' the whole assembly from the vault yesterday.Now i wanna delete the files inside the vault and put back the same assembly once again inside the vault.When i was doing this exercise the above two problems have occured.Plz help me out.....
