I have a question about the connection. I downloaded a new Everquest 2 update and save my previous one. The build is 4607L and server is 4.0
I can login and create a character. But when I want to enter the world nothing happend. No crash, no strange error. I just get disconnected I think, the game is hanging by connecting to zone server when I want to enter the world and then I return to the password screen again. I try it also by loggin to another server that was online and same issue.
My question is...how do you know when the server is not accepting a build because it is to old or to new.

I tested it out. And I logged to a couple of servers.
When I log in with build 4607L on a server with build v 0.0.3 I can login and run around.
But when I do that wit server build 0.0.4 I get an error. And this is the error that I get.
Can you pls look at it LethalEncounter. I know this version is not supported but I can login with build 0.0.3. I am just curious why I can login by an older world.exe and not the newest.
Error: I don`t know what they mean with WS_Skillmap. Is that the sql database??

I found the problem. I see that my WorldStructs.xml file is outdated and read that ont this post...http://eq2emulator.net/forums/viewtopic.php?t=405
After that I tried it again and still an error. I used the world.exe that came from the SVN. So I downloaded the world.exe from the url that I wrote here.
And now it work and I can run around.
Not sure if this is by all builds but I saw this when I loaded up the server. LethalEncounter do you know if that is by all build or is that just because I use build 4607l. I still have the official build that you support so I can alway`s switch back.
But here it is:

Yah that is normal stuff. Unknown opcodes aren't errors. They just mean that nothing was done with it after it was sent by the client.
