I'm sorry, but there's no way for you to restore your data in this situation. You don't have the keys for it. Your IT team does though, and if they so desired, they could decrypt your D: drive.
Even if you had the code of the day, it would not help you - as I say, your IT team has the backup copy of your encryption key in their management system, without that you are sunk.
No, installing it again won't help - because it will create a new key.
Your IT team is the people you need here.
Thanks. I think I will forget about those data. IT team says my situation is not supported by them.
