Crash whilst attempting to render

Basically, beeen trying out the unicorn 3d editor. Is very fun. However, whilst attempting to render a simple scene, i get a rather unpleasant hang. Any ideas what i should try?

Basically just rendering a sphere and an M in a custom font - all looks good until i select "Document" >> "Render Image", then i get a new window with nada on it, no cpu usage, no icon in this new window form, and its caption is simply 'mantissaTest.r3i* - RealWorld Icon Editor' - the window has no "maximise" or "restore" options.

Not seeing a lot of rendering going on, any ideas?

I've got visual studio c# installed, shouldn't cause a conflict with your stuff, and the rest of my 3dhardware is in ok, so help help help 😊
