enewsletter

I'm having trouble with the {subscribe} and {unsubscribe} tags in my newsletter. Is there any detailed documentation on how these links work in enewsletter.

The plugin was setup by a Michelle of northwest media, but I've taken over the web hosting and services and the subscribe / unsubscribe is the only thing I can't seem to get working right. It goes to an error page. So there's something I'm not clear on.

I just bought my own plugin version of enewsletter and hoped to find documentation through that end.

thanks much.
