Enter password to unlock disk not working

I have an external disk that I used for Time Machine, originally under Mavericks on my MBP. I then upgraded to Yosemite and was having issues with the upgrade route and so did a fresh install of Yosemite on my MBP at the advice of AppleCare reps. That corrected the problems with my MBP, however, now I can no longer use my external drive. Once connected I get the dialog box requesting the password to unlock it. I entered my previous login password, my alternate password, new one and just about every password I would typically use (and a lot of their variations) all to no avail.
It is absolutely imperative that I get the data off this drive as I have files that are irreplaceable on it. I have tried going through terminal and recovery mode and using what I thought was the recovery key but to no avail. It's not in my keychain and if it were, well it's on the external drive locked away.
There was an article detailing allowing users to be able to decrypt the drive. Is it because of the fresh install and my account is not allowed why this no longer works?
Is there something else I can try?
Anyone else have a similar situation and solution?
Many thanks in advance.

Just try a Restore with iTunes.
