Hi Cameron, I appreciate your quick reply over the festive period. I am using Windows 10 which is set to synchronize automatically. I have checked and manually synchronized anyway. I reinstalled but Skymax still wont activate. I can go to Gizmo and try also. I get the Activation Successful, Enjoy message every time but also get the Please Activate message every time too. If I unistall my default weather comes back. The Please Activate box seems to have a greyed out password already typed in which is longer than my actual password, I have tried both to activate. There is a machine ID number too. Still no luck though. Frustrated Rik
