Issues Downloading a File From Webhost - RoSESP - Apr 25, 2018

I'm currently using this method to download the dll:

Code 
dll = "(exact link to my dll, i can click it and it will directly download it)" ' Main build

Code 
   Private Sub Inject()

        My.Computer.Network.DownloadFile(dll, "C:\temp\Loader\dll\" + filename)

        'Dim ToHideDir As New System.IO.DirectoryInfo("C:\temp\Loader\dll")

        'ToHideDir.Attributes = IO.FileAttributes.Hidden

        My.Computer.FileSystem.WriteAllText("c:\temp\Loader\Nova.Hook.DLLname", filename, False)

        Timer1.Stop()

        Dim TargetProcess As Process() = Process.GetProcessesByName(TextBox1.Text)

        TargetProcessHandle = OpenProcess(PROCESS_CREATE_THREAD Or PROCESS_VM_OPERATION Or PROCESS_VM_WRITE, False, TargetProcess(0).Id)

        pszLibFileRemote = "C:\temp\Loader\dll\" + filename

        pfnStartAddr = GetProcAddress(GetModuleHandle("Kernel32"), "LoadLibraryA")

        TargetBufferSize = 1 + Len(pszLibFileRemote)

        Dim Rtn As Integer

        Dim LoadLibParamAdr As Integer

        LoadLibParamAdr = VirtualAllocEx(TargetProcessHandle, 0, TargetBufferSize, MEM_COMMIT, PAGE_READWRITE)

        Rtn = WriteProcessMemory(TargetProcessHandle, LoadLibParamAdr, pszLibFileRemote, TargetBufferSize, 0)

        CreateRemoteThread(TargetProcessHandle, 0, 0, pfnStartAddr, LoadLibParamAdr, 0, 0)

        CloseHandle(TargetProcessHandle)

        Me.Show()

        'Dim ToHideDll As New System.IO.FileInfo("C:\temp\Loader\dll\" + filename)

        'ToHideDll.Attributes = IO.FileAttributes.Hidden

        Form3.Show()

        Me.Close()

    End Sub

I commented out the hidden parts so i can easily see what is being downloaded, and it's only 1kb, better yet 841 bytes. Better yet when i edit the dll with notepad++ this is what i get??

The website you are requesting the file from requires you to have Javascript enabled. As you are using a web-request and not a fully-fledged browser, JS is not handled.

You're kind of out of it with this. You have no control over the website and you can't really do a lot about that.

There are a lot of sites (for example Facebook) that give this message if the request was not properly emulated/spoofed.

EDIT: I am not sure what OP means with this so I am not sure if what I said is relevant.

I purchased a webhost and fixed this issue, thank you!
