A pal & myself have spent hours trying to complete the "new" online form for the above. Each time, when we tried to validate it we got a message containing "Error 0115". I read a thread that said it works with Google Chrome, so I installed that browser - still the same result. BUT Chrome told me that I needed the latest version of Java, which I installed and "BINGO" the form was accepted.
So, if you are having similar problems try updating your Java first.
Good luck.
