woocommerce 2… broken

Anyone get an error like:

Cannot read property '94' of undefined on add-to-cart-variation.min.js

I upgraded to 2 and had to roll back to 1.6, which is not the version I upgraded too. It works but looking for version 1.7 (think that was the last one before 2) if anyone knows where I can down it from. I’d like to test out 2 before I make it live.
