Problems rendering with IrenderNXT

Hi all,

I’m having problems rendering a largeish file on Irendernxt program. I put it on low settings, i.e. small picture, low resolution, only three passes.

However when I leave it overnight to render it gets to around 97% complete and then it goes Irender nxt has stopped working in the morning.

I have an ok spec pc:

8Gb ram
i5 7700k processor
MSI GeForce GTX 1050 Ti

Please find attached model:
