HELP - perl script problem upgraded v7.0.7

[NormanRouxel]

said I understand that I copy all the stuff in the original folder and insert it in the 'Site 1' folder, is this correct

No. No-one said that. You have to copy all the files ending in .pl and .pm from Original into your Site folder.

Your version of Windows may not be set up to display the file extensions. A tutorial on how to do this may be better found via Google.
