[Cannot access my account/account on hold.]

I can't enter my account in the site or in-game(It says that either the username or password are wrong).I tried to change my account(even tho i don't recall changing it before) but it says it was put on hold.What could be the problem?Thank you.

That's the problem i have with my main account and not this one.
