That message is old, and if you read the rest of the thread, you would have known that we updated the Live Update to not overwrite the OrbX fix for KLAS anymore, and this was in June. And, the whole thread was about KLAS.
There weren't any problems with KLAX, OrbX and the Live Update but, it's still possible an OrbX AFCAD for KLAX might conflict with it, as discussed in the thread I've linked in my previous post, which refers to some post on OrbX forum related to which files from OrbX must be removed in order not to conflict with KLAX.
