Since it appeared, I couldnt use the default Airbus 310, as everytime selected it caused a CTD, even with MSFS running in safe mode.- I didnt see any thread related, so it seems I am the only one affected.- Any ideas ?

Nope, you're not the only one. Mine crashes fairly frequently too, and when it isn't crashing, it's sucking up the framerates. I've shelved it until a (hopeful) future bugfix, which I hope is coming because other than that, it's really good for a default aircraft.

 

Are you guys sure you're on the latest version? It has to be downloaded from the Content Manager, double check and see if you have.

For me the A310 is flawless, I haven't had a single issue since the last update. Are there any community mods you have related to the A310?

I have installed both versions upto date and have already the problem

I've had zero crashes with it.
