[4.1.1] crash Windows 10

[pingus]

Hello
I'm getting mad with a scene.

Here's our setup : 3dsmax 2017, fumeFX 4.1.1 & licence server
I'm trying to merge a fumeFX into a lighting scene and i constantly crash, while my both scenes worked correctly on each side.

I've try a lot of things trying to make it work, and i finally found out that my scene can be merge & saved on windows 7.
I'm pretty sure fumeFX is not manage the same way on windows 10 than 7, but i don't know why.
I've checked all my firewall or folders permissions..... don't know where to check anymore

Any ideas please ?
Thanks !
