continued frustration and time-wasting

Well, I started an account and accepted its invitation to click on some of the feeds it offered, but when I tried to subscribe by clicking "Subscribe to my selections", it kept coming up with "An error occurred" and a list of incomprehensible numbers and letters. So I presume I haven't managed to subscribe to them, but I don't know why not. Perhaps I'll have to go back to the instructions yet again, and see whether I can find how to get on to the page that's illustrated there. I'm afraid my (originally very slight) enthusiasm for this programme is rapidly waning.
