amigarabita, I know what you mean, trying to figure out those ridiculous, muddled words can be a pain. Once you have entered it in properly (which can sometimes require some guesswork), and have chosen an original name, you should be ready to go. I don't really know what my mean by 'and then makes me repeat this game endlessly', except that perhaps the name you are trying to use has been taken and it wants you to come up with a new one.
Anyhow, I hope this helps, or if not, then I hope you can get some help from the local group.
Amy, welcome aboard, I hope you can put this program to good use
