Where on that page do you go, and what do you enter exactly?
Put tame "distance" in Secret Exponent, and select compressed to view only X coord in Pubkey (after 02/03)
0000000000000000f862dc916dfc4479 -> 02:000002af00818a0d3e8923d211901f7fe7bfd3dc4c604b3e708c2fb4bdd2ed46
I see there is a match in the LSBs:
01f7fe7bfd3dc4c604b3e708c2fb4bdd2ed46
So I take it this was a solved key?
TAME: 01f7fe7bfd3dc4c604b3e708c2fb4bdd2ed46 0000000000000000f862dc916dfc4479
WILD: 01f7fe7bfd3dc4c604b3e708c2fb4bdd2ed46 0000000000000000502a2b5c6849dc12
SECRET_PRIV_KEY = TAME_DIST - WILD_DIST + START
0xf862dc916dfc4479 - 0x502a2b5c6849dc12 + 2**64 = 0x1a838b13505b26867
Does your export strip any information out of original DP files or are you extracting everything, minus the headers?
