(sorry for my english, i will try)

i'm making a game that gets his sources from a FTP server,

The Game download the zip file ( and extract it in the gamefolder
but that is not the problem.

I made a editor for my game, and have a publish option in it; the program wil zip whole the project and upload it to the FTP server, so that the game will update.

with the editor, i can zip the folder.
but i can't open / extract it,
it says = zipfile is invaled

here are my code's of the editor, where the zip is gonna create:
Imports Ionic.Zip

Module Module1

    Public Sub zipp()
        Using zip As New ZipFile
        End Using
    End Sub

End Module
here is the error
(it's dutch, but it tells: can not open the map.
De zipped folder C:\gtamig\ is invalid

please help me,
