Guild Wars 2

hi GW2, i just want to reactivate my account again because i did not Log in for almost a month now because of my busy schedule..The thing is when i log in there is an error saying " Your Guild Wars 2 account has been suspended for an account issue.Please contact Support for information" .
How did it happen, i get all the serial keys to my account..i just want to retrieve my account back to play again ingame..and i already change my password still did not work to log in in the game..
What should i do? i want to play again.

Account issue is in most cases quiete difficult to solve.
Most the time it means AN has not been paid for the game. It might be credit-card-fraud or an error with the payment method of your choice.

Either way you will have to write a ticket to support. “As a question” here: http://en.support.guildwars2.com/
