I paid for the full version, was supposed to be a lifetime subscription. The last upgrade it gave me from v2.17 to v2.67, it says that my subscription is expired and to renew the subscription go to; instanegoogleranker.seoultimatetools.com Which is a dead website. My subscription should have never ended in the first place. In V2.17, the DBC (captcha solving option) didn't work. It did not work with youtube. And support was non-existent. Good concept. Bad delivery and support..
