Edited Issue: Opt In Email issue "Loading" [7479]

Hi there, thanks for your work.
You probably don't want to hear this, but I am still having trouble using CKEditor with the Opt In Email module from DataSprings.

When performing a search in the subscribers list, or trying to update settings in module configuration, the Loading animation just stays up on the screen.

Chrome's developer tools shows this error message:

Uncaught The editor instance "dnn_ctr3793__ControlPanel__EditOptInSettings_txtMessages_txtMessages" is already attached to the provided element. ckeditor.js:285

I'm not sure if this is an issue with CKEditor or Opt In but could you please have a look?

CKEditor 2.00.05
Opt In 4.4
DNN 06.02.05
