[Problems running Jetstream 4100]

Hi am having a similar problem. Am also using Win 7 64 bit. When I installed the Jetstream I also was not asked for the key. When I tried to load the plane a small window appears and says to activate via the internet enter the activation code into the box below. I have then typed in the product key code( as that's the only code that I can find) and hit the activate button. After a little time the box with in which I typed the code becomes blank again and am informed that I have an unlicensed product etc.I have tried several times and I always get the same result. I bought the boxed set from RC sImulations in Bristol UK. Any help or advice would be gratefully recieved. Regards Nick
