Not a crash - but Infinity 1.5.1 suddenly won't launch

A) Yup, uninstalled - reinstalled
B) Yup, uninstalled - reinstalled - then tried a duplicate profile.

All I get is this when I click 'Play' (from the minecraft launcher):

Difficult to confirm without having the full log, but this is likely to be an issue with your nVidia driver (378.49), try rolling back to 376.33

Actually it's not the nvidia driver (ie. I still have 378.49 installed) - it's the 3D driver (of course I uninstalled it, and can't remember the exact name - but after installing that, everything is working again.)
