Thanks, I'll check it out. Although I have a slightly bigger issue, the software really must be a later version than that depicted in the certification tutorial and it this lesson 4 is where I can no longer follow. Could somebody please confirm that this is in fact true, I've flagged this up with 'contact us' people and they've naively suggested to use community support. The problem seems to be far bigger than that and it I can't rely on the online community to complete the certification course.
All information will be hugely appreciated.
