I'm still stuck with G2. I bought G2 and all the add ons, got hooked on multi-fly online, then multi-fly was not supported for G2 anymore. [:@] I think GreatPlanes should of given some kind of warning or option to change order to G3 before I got the program delivered. The G3 program was in the next sale flyer I received just days after purchase. The flyer was probaly mailed the same day as my G2 box. [] I'd like to join you at the online field BUT I'm not payin' another $200 for G3. Anyway, now I'm done complaining. (sorry) Back to the topic: Is the G3 mower useable on G2? If so can I have the link for downloading, Please. I dont have the other sim. Thanks for reading.
