[2005] Runtime Error

[snufse]

I have a windows form that consumes a .dll. (code below). When I run the program it intermittently gives me a runtime error (referring to C++ even if I am only using vb). I am not sure if it has something to do with an email I am trying to send from the code?

We are using Windows XP and IE7.

Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim NewClass As New Asphalt_Plant_Replication_Check.Class1
NewClass.EntryPoint()
End Sub
End Class

Error:
Microsoft Visual C++ - Runtime Library
Runtime Error
R6025
