Mount Encrypted Harddrive in Ubuntu

Hi There,
I'm using HP 2540p laptop with Windows 7 Professional installed in it. I've encrypted the HDD using an encryption software called Pointsec from Check Point. If I'm not mistaken, something happened with my laptop the HDD cannot be removed from the laptop.
The problem is the I cannot enter Windows 7 and always stuck at the beginning. It gave me error message: Pointsec can not load program. I still can access the bios, but cannot access windows. I was planning to retrieve the data using Ubuntu Live. So after I downloaded the iso file from Ubuntu site and burn it to CD, I tried booting from the CD and it works perfectly. Unfortunately I can't find the HDD in the list.
So I opened the terminal in Ubuntu and try to find out if Ubuntu recognize the HDD. I'm using 'fdisk -l' and it resulted in showing all the partition connected to the laptop. But when I tried to mount it to Ubuntu, it always failed. I'm using this 'mount -t ntfs /dev/sda2 /media/sda2'
I've tried several times with different combinations of mount command but it' still not working. Is there anybody who can help me with this?
Thanks,
Raphael.
