ydkm, I am in the same boat.  I think we are out of luck.  There is currently no way that I am aware of to split ETC and ETH.  From what I understand, ETC came out with the most complicated and confusing way to re-reimburse people who had ETC stolen.  That process expired 15 April 2017 (more or less).  There is talk that the deadline was extended but they will only re-reimburse 70% of your investment.  I have seen no developments there though.

I am hoping I am wrong.  If you found a way to split your ETH and ETC please let me know as I have had no luck.

I've tried splitting using Jaxx, Poloniex, Kraken, as well as the REPLAYSPLIT and WHITEHAT contracts.  Nothing has worked.

Best of luck...
