We use Teamraiser software from Blackbaud. The problem is that the primary link is taking between 4 to 8!minutes to download on to desktop systems on our small internal network (30 or so devices). This fault does not occur anywhere else. Phones, laptops, tablets etc. all download instantly, it's just the networked systems in the office. We have also sent links to test sites around the UK and only one problem has been reported which is now fixed. So ironically the only people who can't access the software are the people administering the event!
