What changed?

I've just tested using our 'Demo' account (which is actually a 'real' account belonging to a friend of mine) and all seems to be working fine.
Just to be sure I've also tested with another site that also uses TNT, and no problem there either (radiosailingshop.com.au. Screenshot attached)


Yes the Demo account is working. I believe it is caused by TNTs changes over the last couple of weeks.
They have asked me to email them with the calculator code. Do you have anything you would recommend sending them.
