GET A GRIP - They are doing a huge system transition and you say the product doesnt work? So they are having issues getting it up and running in the first 12 hours, big ***** deal, wait until it is officially running and then over criticize.
I will second, third, etc what you say. I've done some massive upgrades myself, and they are sometimes no fun. I hope these guys are getting free pizza and drinks while they work. Beer later, when it's running!
