files.py failing when run via browser while properly executed via terminal

[Νικόλαος Κούρας]

i tried somehtign else too.

uploaded 1.mp3 and 1.exe from windows 8 via FileZilla to linux webhost

and then renamed them both  to Greek letters so that the renaming take place from within the CentOS and after that i tried:

http://superhost.gr/cgi-bin/files.py

Guess what? Still same error :(
