it should be x15 not x13 (however if x13 doesn't work, there is little chance that x15 will work...)
You right i was using another version of ccminer, but now the problem is same, nothing change.
I had the same problem mining x13 using ccminer35 and ccminer50, only ccminer30 work on my GTX690 (and ccminer v1.2)
