Enewsletter Creat Newsletter Problem

I am having a problem with the plugin when i try to access the create newsletter, and when i choose and set a different template it show's "Cheatin’ uh?". And also when the editor access the create newsletter it show's same error. I only check all Editor on the User Permission. I tried reinstalling the plugin and also Uninstall option in the plugin but no success..
