Arnold 6 GPU Not working

[Anonymous]

Pretty sure i've got everything setup correctly, specs are:

intel 6800k

nvidia geforce 1080

64gb ram.

For some reason, arnold gpu just doesnt seem to work, i've prepopulated the gpu as said by the docs etc. It just doesnt update in the renderview, ive got all the updated drivers too so it can't be that. Any help would be much appreciated, i dont get any errors in my script editor either.... it just says 'rendering......' and stays like that (been an hour waiting now).

And a single sphere with zero lights and materials in scene also wont render?

If you try to funnel in an old scene with a ton of unsupported items, it can stall easily.
