Welcome to my hell.  All of our laptops have Pointsec on them, it makes support difficult.  
You can put the drive in another computer to attempt a recovery though.  If it's a desktop you'll have to connect it with SATA not USB, or if it's a laptop you'd need to put the disk into a drive sled.  The Pointsec version on the host computer needs to be the same version as the drive you're slaving.  Once you do that when you boot you should get two password prompts, one for the host computer and one for the slaved drive.  Log into both and you should have access to the drive once Windows boots.  Sometimes you have to set the username/password the same for both drives (use a service or system account).  If that doesn't work, your only option is to have someone with the access use the recovery file to decrypt it.  
I had a drive recently that was locking up right after Pointsec.   Nothing we tried would get it past that point.  So I was going to have Pointsec removed, but we could not locate the recovery file.  The Pointsec support people couldn't even help us at that point.  I ended up having to just reimage the drive.  Unfortunately the user didn't bother backing anything up to their network drives, all their crap gone.
