now they want me to do offline activation...i only have one computer and it's online and i find it difficult to understand.....afraid i'm tired and i've lost patience and will forget about capt.sim....at least i got a decent 737 .....so i can't complain....win some loose some.......have to say though....in my whole 71 years, i haven't had so much frustration with anything as i've had with cs....it's almost comical......like someone pulling my puppet strings and saying dance, dance, dance.....................and i dance......but i broke my heal..... ;D

You can do offline activation from the same computer that the aircraft is going to be installed on! I do it all the time, even though there are 4 computers in my computer room and they are all connect to the internet. :o
