************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

this is on my email bomber, can anyone help?

Okay, here's some code I used in an old project, a very generic email function:
[highlight=vb.net]
Imports System.Net.Mail
Imports System.Net
[/highlight]

[highlight=vb.net]
Public Structure SmtpServer
Public Shared LiveSmtp = New SmtpServer("smtp.live.com", 587, False)
Public Shared GmailSmtp = New SmtpServer("smtp.gmail.com", 587, True)

Public URI As String
Public Port As Integer
Public UseSSL As Boolean

Public Sub New(ByVal smtp As String, ByVal port As Integer, ByVal ssl As Boolean)
Me.URI = smtp
Me.Port = port
Me.UseSSL = ssl
End Sub
End Structure

Public Function SendEmail(ByVal message As String, ByVal accountInfo As NetworkCredential, ByVal recipients As String(), ByVal sender As String, ByVal subj As String, ByVal server As SmtpServer)
Dim nMail As New MailMessage
Dim smtpServer As New SmtpClient(server.URI, server.Port)

nMail.Sender = New MailAddress(sender)
nMail.From = New MailAddress(sender)
nMail.Subject = subj
nMail.Body = message

For Each s As String In recipients
nMail.To.Add(New MailAddress(s))
Next s
Try
smtpServer.Credentials = CType(accountInfo, ICredentials)
smtpServer.EnableSsl = server.UseSSL
smtpServer.Send(nMail)
Return True
Catch ex As Exception
Return False
End Try
End Function
[/highlight]

Example use:
[highlight=vb.net]
SendEmail("Hello World", _
new NetworkCredential("foo@gmail.com", "bar"), _
new String() { "fake@live.com", "joke@hotmail.com" }, _
"[MPGH]Jason", _
"Testing Email", _
SmtpServer.GmailSmtp)
[/highlight]
