I test Nod right now, for the first time. I am very pleased. I have 2.7 trial with 1 day left. (BS-settings, not scheduled) Now i want full version. Control Center has this option: Update - Full version - Buy now. It says all my existing settings will remain unchanged. Please tell me, does this work? All I have to do is follow the instructions? Nod work so fine on my computer, and I dont want to mess up.
