WOW -- check this Cirrus Sim Plane out...

If in doubt, just redownload and reinstall which quite simple to do with our use of F1 wrapper system. This will insure that you have the latest file which contains all enhancements to date:-)By the way, this is the same for all of our aircraft. We choose to "roll updates" into our downloads rather than having service releases floating around which complicates users ability to keep themselves current. This way, redownload and reinstall is all that is required by the user.As always, one should backup any personal user customization before doing a reinstall. Hope this helps:-)
