Hello,
I have started a triial of DotNetNuke and I have added the HTML module to the page which is fine. I then go into edit the text content, I can either select Basic Text Box or Rich Text Editor.
If I select Rich Text Editor this is what it says:

Could not load RadEditor. Culture is not supported. Parameter name: name [Setting.D is an invalid culture identifier.

Does anyone have an Idea why this is happening.
I am using DNN4FREE to run my trial. As I am only an administrator on the website I can not tell which version it is running.

Regards

Keith B.
