Unlock All Classes?

I used to play on the steam client using my steam account

Now I use a hacked client, so as far as I know I can't use my steam account. I have to make a new account and unlock all the classes again.

Is there any way to unlock them all straight away?

(Or a way to use my steam account on a hacked client).

Thanks.

If you want to unlock them again then just play the game.

Or make a web account and link it to your steam account on the web client. And thus play hacked client with steam profile account.
