As Ast said, there was a great reset that most things such as; In-game score, weapon skills, vehicles, etc.. were reset in the process.
The link below, you can see more information about the matter to catch you up.
As far as your account, I'd suggest hitting up an Admin/Manager about it to sort this situation out for you. Or if need be, you can request a "Password Reset" in one of the links below that I've provided.
I hope this information was helpful. I'll give you time to reply to this post before locking it. Just in case you have any more questions pertaining to your situation.
Best of luck to you.
