I had a friend who comepletely got out of the hobby and I purchased everything he had concerning rc related items.In my inventory was a cd that says (real flight deluxe) on it.I also have a transmitter with a computer cord attached.I have 2 more add-ons disks also.Anyway,my question is this.I put in the (rfd) disk and then go into the aggrement then I say yes then it ask's for name and serial number,and if I bought the interface list the serial number for that.There is a number on the disk.Is that it?Also,on the pop up box I am typing this into it has a next button and back button at the bottom.After I input my name and that number,the next button will not do anything.What do I need to do?Is it legal for me to have this?Thanks for any help.Tivey
