I bought the CF106 for XP after reading the review here on SimHQ. The stupid copy protection system requires you to email the owner with a serial which you get after you installed the aircraft. So for me and Canada being almost exactly on the otherside of the world I fired off the email and got the response a day later.

I used the aircraft for one day, switched off and went to sleep. Yesterday I booted up XP and after having read the manuals now was going to go in depth with this bird only to find the gauges again not working and it says the aircraft is unregistered once again.

The serial number somehow changed but I have not added anything to my system or made any changes for that matter. So I emailed him again and I'm still waiting for a reply!! Man that sux!

Ever get this figured out ? Had some issues with to until I re-read the instructions to activate. Found I must have the License text file with serial code saved
in each plane and the main X-plane folder. Then it all began to work. Making sure you save the text file after pasting in the serial code. Hope this helps.
Greg Hoffer has been a friend of mine since 2000.

Must admit, he came to the party bigtime and it was sorted and everything now works. Something to do with the way my network is setup apparently but he gave me a solution that worked. My bad for not reporting back and I must apologize for my tardiness.

No problem, I knew Greg would help out and you up and running. Enjoy the F-104, its a blast to fly.
