Account blocked by error host.

Hi, yesterday afternoon when entering my account ,i received an error off and went offline.
when trying to enter again. I received a warning that my account saying "your account has been blocked by 0 days,0 hours,0 minutes" LOL?? (O.o) I try to enter again and can normally play..
Today I spend exactly the same as yesterday, but during a game of team deathmatch.I got an error saying "host error" and then i had to close crossfire from task manager. when I try to enter to my account, receive a notice that "my account has blocked by 0 days,0 hours 59 minutes" LOL. I really have nothing. I mean also these problems started after the last update -patch.
