I just wanted to send a thank you to you guys for developing this software.My wife's school computer lost something in the windows files and started to fail to boot properly. She is in charge of some critical projects and had not backed up active files she was working on. I was able to use the OSX Bitlocker utility to unlock the drive (with help from the schools IT) and mount it to my Mac and viola we had her files back. This was so easy to use and it just worked wonderfully. Thank you guys all so much for the work you put into it.
