Re: cannot publish and have published before...
If you see any green bars then that proves you ARE entering the correct info and that the program IS working. Lady Eye above is correct in saying to you that it is your internet connection. Don't worry it happens to most if not all of us at some point. I use Tiscali for my sins and have no end of problems publishing! Just keep at it, it should go through eventually.
Don't aim for success if you want it; just do what you love and believe in, and it will come naturally.
