Alan Practise Tests Site not Working/Shockwave issue

[jamie-a]

I`m having trouble with this site http://www1.edexcel.org.uk/tot/alns2/CMA-Edexcel-web2.swf not working for some users, it doesnt seem to be a plugin issue as it works fro me on one pc but not for my test account, I dont think its a profile issue as the teacher who reported said it works for some students but not others and they are on mandatory profiles. Its not a firewall issue has anyone any ideas?

 

Thanks in advance
