New player joins host problem

[Thijs-boy]

I have a problem, if a new player joins the host, I get a error: NCN - Index & length must to a location within the string related.
Parameter name: Lenght

I've copied the orginial NCN of Open Source InSim, but still got the error, here I've my code:// A new client joined the server.
private void NCN_ClientJoinsHost(Packets.IS_NCN NCN)
{

Who can help me?
Thanks

Could you provide a little more details please?

Like:
What are you using as a base? Meaning - what are you using to build up your insim app. from?
Exactly where did you copy the code from?

How have you made sure the new code is compatible with the current source?

I think that should be enough for now. :)

[Thijs-boy]

I'm using Visual C# 2010 Express
And I copied the code from .NET (C#) - Open Source Cruise Server, dougie-lampkin

Okay, but you misunderstood my initial question. Let me ask in another way: Where did you download the source, you are copying to?

[Thijs-boy]

I downloaded this InSim http://www.lfsforum.net/showthread.php?t=43103 and I was going to edite this to my own, I have nothing did with the NCN part, only the name changed.
I was adding a new command or something, I build the InSim and get this. Its weird but some players see the insim, and other players not.
