Thanks for the quick response,
I shall get us both updated to the latest build/
There are no compiled nodes, and so it is strange that I am having the crashing problem.
Additionally there seemed to be an extra folder included called MacOS something or other, which contained some binaries and a couple other folders that I imagined should have been kept in the main project folder. Odd Mac stuff.
I shall look into using Git.
