Soldiworks mysteriously crashing

I am making a cam follower model and when I try to make the mechanical mate between the followers and the cam; Solidworks crashes. I have been getting messages saying memory is low on other projects I have done but no crashes. My rig is built way above what i need to run Solidworks. Anyone had a similar experience and or fix for this issue, please help.

Kind Regards, Jason Poole.
