I quit with this kind of coin.
I tried different miners: yacminer-3.3.1, yacminer-3.4.2, cgminer-3.7.2-sj-0.02 and other modified scrypt-jane miners + many different settings and nobody works.
I got only windows freeze and have to restart my computer.
For me it's a waste of time.
My GPU: PowerColor R9 290X
if someone with this GPU brand is able to mine scrypt-jane coins please sent me a pm with miner and command line.
Thank you and bb, I'm go to mine other coins.
