Windows 8.1 PRO unable to unlock Bitlocked drive

Can you take a screen shot of the bitlocker window?

Also, what happens when you highlight the drive in This PC and go to the Manage tab? There should be some bitlocker options there.

As you can see Drive D is no longer present in BitLocker Drive Encryption.

When I click on this Drive under Explorer I got the option to FORMAT this Drive and when I click cancel I get the following.

Windows 8.1 PRO unable to unlock Bitlocked drive

I used a Bitlocker in Windows 8 PRO to Lock my Internal SATA Drive. I have formatted my PC twice in past and I was able to unlock it after each fresh installation of Windows 8.

But Recently I did a fresh Installation of Windows using same Software and CDKEY. This time I did upgraded to Windows 8.1 including all the latest patches.
Problem is When I click on my Drive, Windows give me the message " DO YOU WANT TO FORM IT" When I do click Cancel. I do the following message "The
volume does not contain a recognized file system....."
Here is the screenshot of error message

Disk management shows a healthy Drive:

I have done fresh installation of windows several times before but never had this issue. I was always able to restore security settings and unlock my drive using BITLOCKER.

I have tried to unlock the drive with just Windows 8 pro and the problem persists.

Additional Info:
- Control Panel > BitLocker, Software no longer shows my drive under it.
- Hardware specs remain the same before or after the issue.

Any tech support would be great.
