education training courses not launching, just sits at the learning.emc.com address

i goto education.emc.com, login and under my account goto my training, select any of the courses there to launch into the online training and it opens a new window then just sits there with a white page and does nothing.

this was working yesterday i did 9x online training courses.

i have 2x left i want to complete urgently today please.

i have cleared my internet cache, reset all defaults on my browser(IE) and rebooted my laptop etc

i have tried from a home network and from our work network, also tried from our terminal server, my laptop and a test machine.

my work mate who is at home today and has also been able to do the training in the past also is having trouble getting on today both in IE and in firefox so it seems a site issue not an issue with my laptop etc.
