Im able to get to character screen but then, im always getting an Error message saying : Error : An error has occurred. Please wait a few minutes and log in again.
It all begin since they charged me for the month.
nope, been fine. Have you checked your account on the eso website to make sure you have a valid account and subscription? Maybe they messed something up
another thing I'd try is disabling all addons and try to login and see if that changes anything.
Do you get this error messege before the character seelct screen or after selecting a character and trying to enter the game?

Disable your addons and log in. Should get you in and then you can go back and try logging in after enabling a few addons at a time. I had this issue and found that is was ESOHead causing the issue for me.
