This is my first guide...YAY me..lol,
Any ways i was messing arround with the logon.conf
and changed the Client Build, Here is what i did to make it 2.3.3
This is what it looks like when you first get it.(before Changes)
<Client MinBuild = "6739"
MaxBuild = "6739">
Ok now you change the MaxBuild to 8500, Thats it. ^^
End result.
<Client MinBuild = "6739"
MaxBuild = "8500">
And now your server is 2.3.3.
