[RESOLVED] Unexpected Error

[rafhelp]

Ok i made a program it worked fine. I changed Net Framework to 3.5, then back to version 4 (i was testing something)

It now works fine.

I run the program from vb.net in debug mode and everythign works fine.

I clean the build,

I then build the project.

I then run the built exe but then it shows an error. The error point to this code:

    Private Sub Form1_Load(sender As Object, e As System.EventArgs) Handles Me.Load
        If Not My.Computer.FileSystem.DirectoryExists(wdir) Then
            My.Computer.FileSystem.CreateDirectory(wdir)
        End If

        If Not My.Settings.prevsearch Is Nothing Then
            If My.Settings.prevsearch <> "" Then
                txt_g_url.Text = My.Settings.prevsearch
                MsgBox(wdir)
            End If
        End If

        For Each item As String In My.Settings.prevurl
            If Not txturl.Items.Contains(item) Then
                txturl.Items.Add(item)
            End If
        Next
    End Sub

I cant figure out why this is. The main point is it works in debug but not after its built.


heres the exception error:
