OK what has changed or gone wrong, My C130 all versions now loads then after a few seconds leans to the right as if the undercarriage has failed.

I have unistalled , reinstalled the product, none of my other payware does this, and i am loathe to have to completely rebuild my FSX as my setup is finally working how i wanted it, with 25+ payware aircraft products and many more scenery addons, this issue only started last week, nothing has changed on my PC apart from the 1903 windows update.....

Arrgh any help would be appreciated
