First, I am new to SCCM and I am using SCCM2007 SP2 w/o MDT integrated.  I am following the steps given in Customizing Windows 7 deployment - part 5 and I am running into the following problems: 
  
1.  I cannot import the "Deploy Windows 7 Ent X64 - BITLOCKER in WinPE.xml" file 
2.  I completed all of the steps outlined but I'm getting an error at "Set BIOS Password" but If I go into options and select "conitnue on error" it goes thru and I then get an task sequence error on " Prepare Disk for Bitlocker" and it completes w/o bitlocker being enabled. 
  
I have followed the task sequence step-by-step but I'm not having any success at this point.  Any help would be greatly appreciated!
