Seems I am having extreme difficulty making the Dream Fleet products work. Initially I purchased the Archer III and it did not work with FS2004 (Ticket 3GTX6729135). I then purchased the Dakota for FSX two days ago and I get the same Garmin Error, "Reality XP Garmin GNS 430 Version 188.8.131.52 can't start the Reality XP Garmin Error 3524" and then FSX shuts down. I really like the look/function of these products but don't understand what is happening. I am running Windows 7. I don't see any mention of your products having any compatibility issues with Windows 7. Any ideas?
