Can't play the server

As stated in the support section, I changed the country to north america (united states, as it is listed), however, I was not able to open the game for it still says the country is not available, I reinstalled the launcher of yours, and still could not open the game, later on I found that NCSoft launcher does not have Aion in the United States setting, I'm not sure if it makes a difference, and so, I need assistance with said issue.

 

Your version might be 4.5.0.14 if its over you must downgrade it, Here the guide: http://forum.gameznetwork.com/f64/[important]-downgrade-4-5-0-15-4-5-0-14-a-178425/#post1743286

If your version is right this should help you.

1. "This program is unavailable in your country." (Error picture)
   Go to Aion\L10N\ENU, select everything inside that folder (Ctrl+A) and copy that (Ctrl+C), go to Aion\L10N, select the folder of the language your windows is using and paste what you have copied in that folder (Ctrl+V), run the Gamez Aion launcher, update if asked, and play.
   Language and folders are right here:
   • FRA is French
   • DEU is German
   • RUS is Russian
   • ENU is English (USA)
   
   
   If that doesn't work, delete the L10N folder from your client and repair it with the NCsoft launcher, after it's completed check if the client works clicking on the blue button that says "Play Now", if it works and your Windows uses any of the 3 languages listed above (excluding english), then you may need to do what I stated above.

 

Thank you for your quick assistance, I'm afraid none of the languages listed are my computers language, for it is spanish.
Does that make any difference or problem whatsoever?

 

If you speak spanish i can help you via pm, im from venezuela.
