Crashing or stalling

Hello All,

I have just downloaded and installed SnSpro for Rhino 7 and have been getting some very mixed results so far.

This plugin seems absolutely perfect for what I am trying to do but I am struggling with crashes and stalls every time I change the resolution above lowest.

It sometimes eventually gets there but it takes a very very long time and seems to not use many system resources, is there some way of using more processing power? My machine is lightning fast and it doesn't seem to use any of the available power.. 

Tia
