You, more than likely, had an illegal activation on your Windows to begin with. KMSClient indicates that. That's why you can't activate it now. Going to have to research how to clear the KMS activation method.....
maybe @Superfly will come along and post how to clear the MKS activation method, then you can use the dreamspark product keys to activate it legitimately.
Or you can wipe your existing Windows 10 and do a clean install.
