Hey, A friend offered me a v3 probe, and I am currently playing around with it, exploring what I can do. I think there may be a bug in the measurements setup process. When I try to add a measurement, I get a message: "AccBalance matching query does not exist." This is not a very user friendly message. Perhaps this is suggesting that I don't have enough credit? This leads me to another potential problem. On the landing page, after I login, there is a credit summary consisting of two icons and a kind of pie chart. If I mouseover "current balance" it says 0. If I click it, the resulting page says I have 50,000 credits (the welcome bonus). I suspect that I can't setup the measurement because some part of the system thinks I have no credit.
