Just update the game in the normal way. Then close the launcher and turn back to your Aion folder where you can find the versionInfo_AION.ini and turn every value to 3, so that the file looks like this:
[UpdInfo]
CurrentVersion=3
SeparateStatus=3
UpdaterVersion=3
And don't delete the CHS.pak. It didn't work for me when i delete this data but it works fine if the data is still there.
This should solve the problem
So, jetzt sollte jedem geholfen sein ^^
