I've also had alot of issues with these ECDL tests. As usual they gave me the lazy answer of 'Its something with your network'. I had the issue of the 'Processing' page when students would attempt to go to the next question. The only fix for this was to reboot the PC and resume the test. I have tried both with Java and the EnlightKS Plug-in and I still have issues. I hardly get a response from technical support. The head of ICT has phoned them up as well but they don't seem to have a clue and are not helpful at all. Ive sent them screenshots, error logs yet they fail to respond back. And to put the icing on the cake, today the students were in the middle of an exam and all of a sudden the tests all froze with a network error message. They must have been an overload on their servers. When I tried to ring their technical support I got the automated message 'we are extremly busy please email us or use the chat function'. Absolutely useless. And the worst thing is that we have 120 candidates taking these exams which count towards a GCSE.
