If you go to File > Connect

You should see the problem.. have NO Clue why this happens

After an arduous debugging session (you really should try it some time), I found the cause of your problem.

frmMain.vb:

[code]
Private Sub sckBNLS_onConnect() Handles sckBNLS.onConnect

AddChat(rtbChat, Color.Green, "BNLS: Connection Established!")

Dim packet As New BaDDChaT.BNLSPacket(&HE)
packet.InsertBYTE(&H0)
sckBNLS.SendData(packet.Data)

End Sub
[/code]

Step down into Sub New of BNLSPacket(ByVal Byte)

PacketBuffer.vb:

[code]
Public Sub New(ByVal PacketID As Byte)
MyBase.New(PacketID, Medium.BNLS)
End Sub
[/code]

Looks right. Go to the base:

[code]
Protected Sub New(ByVal PacketID As Byte, ByVal ServerType As Medium)
m_packetId = PacketID
m_medium = ServerType
End Sub
[/code]

You forgot to call the parameterless constructor! This can be corrected by updating your sub (here) to:

[code]
Protected Sub New(ByVal PacketID As Byte, ByVal ServerType As Medium)
' LOOK HERE!
Me.alBuffer = new ArrayList()
m_packetId = PacketID
m_medium = ServerType
End Sub
[/code]

With as much as I've helped you up to this point, you ought to put my name right around the top of your "thank you" list. :-P

[edit] And update your buffer so that it's not using ArrayList! Make a ByteArrayList or something! That way you don't need to deal with boxing and unboxing the value types of Byte within the ArrayList (because internally it's stored as Object, which is a reference type.... You'll get about 5-8 wasted clock cycles every time you convert between Object and Byte). [/edit]

Don't Worry!

Your gonna be Commented Lots =)
