ionCube Loader problem

hi there.i find this software really interesting. i tried to install the trial version. did as manual was saying and run the tester and got that

However when i finish the setup, (click this link to continue) i get this error
"The file /home/httpd/vhosts/mysite.gr/httpdocs/amember/index.php cannot be decoded by this version of the ionCube Loader. If you are the administrator of this site then please install the latest version of the ionCube Loader."

Can anyone give me a clue?
