Errors after installation - missing files in includes folder

[pr0fess0r]

Hi Guys

I've installed this on a 1.9.2.2. server from a number of sources and followed the instructions on this page for manual installation: http://www.aschroder.com/2010/05/installing-a-magento-extension-manually-via-ftp-or-ssh/

But the files supplied only include an /app folder, and the errors I'm seeing (I get 500 errors when I try and access the extension) are like this:
Warning: include(/chroot/home/livewire/livewiregames.co.nz/html/includes/src/Aschroder_SMTPPro_Model_System_Config_Source_Smtp_Authentication.php): failed to open stream: No such file or directory in /chroot/home/livewire/livewiregames.co.nz/html/includes/src/Varien_Autoload.php on line 94

How do I resolve this error? Do I need to put other files into /includes/src ?
Is there way to install the latest version via FTP that doesnt result in this error?

Cheers :)

Hi @pr0fess0r, unfortunately I do not have a server with ftp to test this out but following these steps on a local machine it works for me. Can you verify the files are placed in the correct directories and have the right permissions and owner?
