[Solved] licence problem

hello,

i just bought a license for cKfinder.

After downloading the latest version i realized i'm still running on php4 on our server so i returned to download an earlier version of cKfinder.

all works but i'm getting the 'this is a demo version' message on using and uploading.  I put however my license name and key in the config.php page.

print screen in attachement.

thank you for your quick response.
