Windows 10: Forgotten password for Microsoft account/Bit Locker Encryption Key

My laptop has locked me out due to a registry error. This has resulted in a request to enter my microsoft account log in. The problem is, I haven't used the log in for ten years. The account log in is an @btconnect.com address. Microsoft has withdrawn those accounts so I don't know if I can even reset the password?? I have tried the reset options but the verification questions asked are ridiculous; I can't answer them. If they were asking the names of the devices it's been used on, it would be ok but questions about emails I sent over 10 years ago or skype contacts from the same period are ins

Bit locker Encryption

Hello Fiends,

Actually my problem is that i have previously installed windows 7 ultimate(32 bit) in my desktop and to protect my data,
encrypted the "D drive" using bit locker, then after few months, i installed
windows 10 pro(64 bit) in my desktop without disabling the bit locker, after installation i was able to access my locked drive with same password.

Till here everything was fine, but after some days my Desktop started to lag then again i switched to
windows 7 ultimate(64 bit).

But Now i'm not able to access my encrypted drive which was locked by bit locker with same password.

While i'm trying to unlock the encrypted drive i'm getting the massage as
"Unable to Complete the requested operation because of either a catastrophic media failure
or a data structure corruption on the disk".

Pls Help.

Thanks.
