I also used my 5 attempts up yesterday. I'm getting the impression that you do not need to answer all of the questions, despite the fact that the system asks for the answers - so you just enter your name and UCI, not the PR date, country of birth, etc. Can anybody comment?
Also, if it is the case that the system doesn't want the family name, despite asking for it, in what way should the name be set out? John Smith? Smith, John? My surname and first name are separate items in my passport.
Hard to belive this crap system is only 2 years old...
