[Plugin: WP Responder Email Newsletter and Autoresponder Plugin] Can't change the email message

Hi,

I installed the plugin and everything works fine, but I can’t change the email messages that are sent out to a user who has subscribed to a newsletter.

I know, I can set up my own subscription and confirmation message, when I generate a newsletter, but the plugin doesn’t take my text, it falls back to the standard messages. I even changed the files, that are saved in the “templates” directory, but it didn’t help.

Any idea, why this is not working?
