Could someone tell me how to fix it?

my friend had the same problem. in C:\Users\USERNAME\AppData\Local\Akamai you need netsession_installer.exe and run it when you do. http://client.akamai.com/misc/demos/BasicDownload.html

Still going on the same

Never use something from aeria site. Akamai is a bugged/useless/suspicious application, use google to find the archive and just download it.

http://www.gamona.de/downloads/alliance-of-valiant-arms,full-client-januar-2012:download,2033073.html for exmple

and download the patch after, but install it on a DIFFERENT FOLDER or the patch delete the files.

I have the same problem !
Really **** migration !!!!!!!!!!!!!!

I have uploaded the installer to a mirror site for your convenience.

EDIT: It has been requested that I remove the mirrors. Only official downloads are supported.

Enjoy.
