Trouble Authenticating with WP remote login request - vb.net

Question

Okay so I was going to post this on the last 3 errors I got, but I fixed those all(thankfully). I no longer get any kind of cookie blocked message, however now I get a Error logging in whether I'm putting in the correct password or an invalid one. I think its either
A. a cookie storage error.
B. or a problem with redirection.
Imports System.Text
Imports System.Net
Imports System.IO
Public Class Form1
Dim logincookie As CookieContainer
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim postData As String = "log=" & TextBox1.Text & "&pwd=" & TextBox2.Text & "wp- submit=Log+In&redirect_to=""http://csvlife.com/wp-admin/" & "&wordpress_test_cookie=1"
Dim tempcookies As New CookieContainer()
Dim encoding As New UTF8Encoding
Dim byteData As Byte() = encoding.GetBytes(postData)
Dim postreq As HttpWebRequest = DirectCast(HttpWebRequest.Create("http://csvlife.com/wp-login.php"), HttpWebRequest)
postreq.Method = "POST"
postreq.KeepAlive = True
postreq.AllowAutoRedirect = True
postreq.CookieContainer = tempcookies
postreq.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b6pre) Gecko/20100903 Firefox/4.0b6pre"
postreq.ContentType = "application/x-www-form-urlencoded"
postreq.Referer = "http://csvlife.com/wp-login.php"
postreq.ContentLength = byteData.Length
Dim postreqstream As Stream = postreq.GetRequestStream()
postreqstream.Write(byteData, 0, byteData.Length)
postreqstream.Close()
Dim postresponse As HttpWebResponse
postresponse = DirectCast(postreq.GetResponse, HttpWebResponse)
tempcookies.Add(postresponse.Cookies)
logincookie = tempcookies
Dim postreqreader As New StreamReader(postresponse.GetResponseStream())
Dim thepage As String = postreqreader.ReadToEnd
If thepage.Contains("ERROR") Then
MsgBox("Error logging in!")
Else
MsgBox("Lets Start Blogging!")
End If
End Sub
End Class
I have my fiddler open and I've logged into the page and noticed that when I login regularly from by regular browser
fiddler will show this:
then the results come in and it looks like this:
Clarification: The pictures above is what the web traffic info looks like when I login from any basic browser on my computer
Here is what it looks like what I login from the program:
Always an error.
And the request number is just 200 no 302 before or after.
However when I try through my program the req number always remains 200 which is post. Its like it never gets to redirect and I don't know why. Notes: This is my website and this not for any kind of malware or whatever. Its just for blog automation. If there was anything else I could find on this matter I would. At this point I have no other option. Thank you kindly for your help and consideration.

In line 9:
Dim postData As String = "log=" & TextBox1.Text & "&pwd=" & TextBox2.Text & "wp- submit=Log+In&redirect_to=""http://csvlife.com/wp-admin/" & "&wordpress_test_cookie=1"
The parameters to be sent with the post need to be separated with an ampersand, as written the password parameter has "wp- submit=Log+In&redirect_to=http://csvlife.com/wp-admin/" appended to it.
Assuming wp is a parameter:
Dim postData As String = "log=" & TextBox1.Text & "&pwd=" & TextBox2.Text & "&wp- submit=Log+In&redirect_to=""http://csvlife.com/wp-admin/" & "&wordpress_test_cookie=1"
