Another awesome post!
I was asked to powerlevel someone ealier, and he made me an offer I couldn't refuse. I learned afterwards that He was using an EU account and I am using a US client... We browsed through the files abit and R.I.P. Dodgeme pointed me to LocalConfig.xml So I looked into it.
As of July 19, here is what They both look. (EU and US) And I say As of July 19 because there is a Patch Version number at the bottom that changes every time there's a patch. I'll include it in this one, but DO NOT CHANGE THIS LINE (RED LINE) IN YOUR LocalConfig.xml OTHERWISE IT WILL SAY YOU HAVE A CORRUPTED VERSION!
US:
<HttpPatchAddr> http://aoc-us-update.live.ageofconan.com/upm </HttpPatchAddr>
<ClientHttpPatchAddr> http://aoc-us-gameupdate.live.ageofconan.com/upm </ClientHttpPatchAddr>
<ControlHttpPatchAddr> http://aoc-us-control.live.ageofconan.com/upm </ControlHttpPatchAddr>
<HttpPatchFolder> AoCLiveUS </HttpPatchFolder>
<UniverseAddr> aoc-us-um.live.ageofconan.com:7000 </UniverseAddr>
<DevName> conan </DevName>
<UniverseVersion> 2 </UniverseVersion>
<PatchVersion> x8069692616b46f787d6f5204192761c8 </PatchVersion>
EU:
<HttpPatchAddr> http://aoc-eu-update.live.ageofconan.com/upm </HttpPatchAddr>
<ClientHttpPatchAddr> http://aoc-eu-gameupdate.live.ageofconan.com/upm </ClientHttpPatchAddr>
<ControlHttpPatchAddr> http://aoc-eu-control.live.ageofconan.com/upm </ControlHttpPatchAddr>
<HttpPatchFolder> AoCLiveEU </HttpPatchFolder>
<UniverseAddr> aoc-eu-um.live.ageofconan.com:7000 </UniverseAddr>
<DevName> conan </DevName>
<UniverseVersion> 2 </UniverseVersion>
<PatchVersion> x8069692616b46f787d6f5204192761c8 </PatchVersion>
Just copy paste all the info (exept PatchVersion - Leave your current Patchversion untouched, even if its not up to date, it'll get the patch from the patcher if you're missing something.) of the server you want to play on (US or EU) and paste it into your LocalConfig.XML (You can open it with Notepad)
There you go, you have it, US client playing EU server and vice versa!
