Prepar3d crash after loading traffic when slowing time accel.

Hi.

I've been having a problem since p3d v3.2 whereby after using time accel greater than 4x speed. The game crashes. This happens using even the default aircraft and default scenery. It doesn't usually happen the first time. For example when doing a long haul flight i may use time accel to around 8x but slow down to make start a decent. 

Its completely ruined the sim for me since 3.2 came out. I did start a topic on the official forum but to no luck. I have now done a factory restore of my pc but the problem still exists.

If anyone could assist please?

thanks
