Registration process is fatally flawed

The registration pop-up asks for an ID which has not apparently been provided as part of the d/l so how is anyone supposed to know what to insert? Thinking maybe it was user selected, I put in an ID, then repeated it for the on-line name, then typed in a new password and email and hit enter. Nothing happened. I tried again but this time I got a message saying I couldnt register again. Registration is such a basic part of using an app, its ridiculous to not have it work properly.
