Variations Not Saving on a Clean WordPress install

just to be sure i installed wordpress 3.4.1 fresh
and woocommerce 2.0.9 fresh

i then created some attributes and attempted to create a variable product

it simply would not save the prices of the variable product….and i have no idea why

ive worked with woocommerce …for nearly a hundred installations
what could be going wrong?
