I did try to import by private keys as well. And after seriously exposing my keys and about an hour of my time... still nothing.
Do the addresses of your private keys actually hold btsx?
- have they hold PTS on the 28. of february?
- or have you donated pts or btc to the ags funds?
- you are a keyhotee founder?
if none of the above you can stop trying, because you just don't have an initial stake ..
further you can also import the wallet.dat file into the wallet which makes it much easier and also is more secure
