When was the refund window opened? Was there an odfficial announcement about its opening?

I like the idea of your project but I am now spooked:

a. All pre-sale payments might have been stolen but for actions of a White Hatter
b. Now, after the pre-sale, you are seeking legal advice about the legality of the pre-sale and ICO of a token that pays a dividend.

Please re-open the refund window.
