I downloaded app on both phone & computer. Won't allow to setup phone because phone is greyed out & says there are no devices to set up. I have a samsung galaxy s3 phone from verizon. I used to have the same exat make & model from cricket which was stolen & then I tried to use android lost & was unsuccessful at recovering my lost phone so I purchased exact make & model from verizon been trying for 2 months to set up new phone but it won't allow me! Help?
