Have you given up on thos post? Can you please address this. Your product does not work in my environment. Not to mention the fact you said you replicated it, therefore:
"I would like a refund of our upgrade from 4.0 to 5.0 - I will keep a license for 4.0 however will be removing your product from the test area of the Defence Restricted network. You told me v 5.0 would work for us, it doesnt therefore a refund is the best course of action IMO, wahts your thoughts on this?"
