Hello All,

This will serve as a formal forum announcement that we have released the version 1.2.3 update for the CL650. All customers who have purchased the CL650 up till now have been sent an e-mail by X-Aviation with complete instructions on how to obtain your update. We have made this a very simple process! For those that purchase the CL650 from today forward, your purchased download will already be updated to version 1.2.3 for you.

REMINDER! Some customers have experienced performance issues where FPS in sim got very low or unflyable. If this has happened to you, please read the following on how to handle the situation:

I have downloaded once this morning 9 hours ago, and once 30 mins ago. I still get the same message. 



Hm, ok, that’s interesting.

If you ignore it and keep loading, which version does the aircraft say it is? Did it install in the correct folder? Did it prompt you to uninstall the older version?
