Last year I have mined around 500,000 ESP1 (Before the hardfork)

Today while I was checking, I found that ESP1 holds no significant value and I am wondering if I can claim any ESP2 from the ESP1 I am currently holding.

I am under the impression that when hardforks happen, I would be holding both coins... But not sure what I should do to get my ESP2

Looking for help on this.

Thanks (Will offer a donation for any help)
