I guess ur Version should be 3.08 from europe if you just arrive.
What you need is a patched 3.03 WOW installed not higher, so you need to check your patch folder of your courrent wow if you have it. Otherwise you need to download the as Blizzard will Patch after reinstall directly to the latest one in Euope.
After you achieve to get the english or any other wow patched to 3.03 check the forum and download the European wow 3.05.exe
And copy it into your wow folder ( dont forget to backup the original one !!!). That will make the deal.
There are more descriptions in here if you look for the 3.00 patch release in the forums.
Enjoy wow and hope to see you on maduolan Shanghai Nr.1 server. Cow Eaters will welcome you look for Juliask, SuzhouAlex
