help with my account!!

hello such a community! can you help me? I can not enter my account !! I tell you…

Yesterday I had some problems with the PC and I had to restart it from the factory, I went back down the game and I wanted to enter and it does not let me say “Password or email account is not valid” …

question!! I enter the page of Gaijin and I can enter as well, change the password, I return to login on the game page. I enter the game and put my email and password and I say “Password or email account does not validate.”

Will the game have been lowered badly? or why will it be ??
