Pmdg737 freezed using ivao

I did flights without ivao, and the airplane flied very well. Today I wanted to do a fly on ivao, but the simulator, using 737, freezed.Solution?

I would suggest asking in PMDG’s forum, or even better, their support desk.

thanks you mortThe2nd, for your fast answer, I posted a topic on pmdg forum also, I will see what they will say to me.

I’m thinking that the problem is addon airport pay lirf. I will try a flight from another airport.
update: I tried on another airport . No problem. I have Lira also, perhaps the problem is between lirf and Lira airport addons
