Is anyone out there who are succesfully mine YACOIN with cgminer

Is it possible to mine it with GPU or only with CPU ?
I cant get cpuminer nor cgminer to work.
Always get error message "no reply by empty server"
or
if hashes, then all package rejected, 0 accepted.
Help or advice (proper settings) needed !!!
Thank You in advance for ur replies...
YAC requires a special mining software because of the n-factor and the scrypt-jane algorithm. It can be download from here:
