Did Paypal take $20 out of your account? I don't see anything in our logs, but I do see a couple of other upgrades that have successfully completed today.
Okay, I found the transfer in Paypal. Looks like you just sent $20 straight through Paypal. That's fine, but if you do it through this page: http://nc4x4.com/account/upgrades it does everything automagically.
