FSPX causes CTD on a specific site?

[Nfus]

During the past week I have been flying always the same route fromm EGLL to KJFK with my LVLD763.

Here the flight plan if anyone wants to test it:

(WOB2G WOBUN DCT WELIN UA2 TNT UP6 MIMKU UN563 PIKIL 5623N 5532N 5441N YAY J553 YNA J549 CL J564 PQI J55 ENE
ENE4 CCC ROSLY ZALPO ILS22L).

I kept one experiencing CTD roughly always at the same site: during the legs from 5441N to CL.
As told before I've been flying this same route for a week as Im trying to understand why my FSX keeps on crashing!
I changed plane, graphic setting, Airac cycles and everything possible but FSX kept on CTD.
Then I tried to fly without FSPX and UNFORTUNATELY my flight ended ok. I say unfortunately as I really did not want FSPX to be the
possible cause of my troubles at all!
All CTD where due to .dll files: from terrain.dll, to ndll.dll, weather.dll and other .dll that I cannot remember now.
Anyone of you can maybe have an idea on how to solve this issue?
Flying without FSPX is really not worth it...

Thanks in advance

You've tried multiple flights with this route without FsPX or you just did one flight?

At the moment only today flight has been ok but all 6 before made with FSPX had crashed.
I will try again the same flight whitout FSPX, do you recon I should use always the same plane or change it instead?

Well, I don't know if I could attribute the problem specifically to FsPX. Do you have other scenery addons,too?
You could definitely try different aircraft on the same route with FsPX and see what happens.
