The CuteEditor for DNN 4.x download link is http://cutesoft.net/downloads/folders/cute_editor_current_releases/entry21905.aspx, I just tested it, the built-in temporary license works fine.

 

I sent you one valid temporary license, you can use it and let your site work. Please forward your email receipt to eric@cutesoft.net, I will tell you how to go ahead and get your permanent license.

 

Regards,

Eric
