Yes. I also cannot get the SL viewer to load with Windows 10. It crashes shortly after I put my password in, sometimes almost immediately, other times after a few seconds. And the Singularity viewer has been showing me, as a Classic avatar, wandering around with a large house attached to my wrist. All I myself see is a white cloud. I have just downloaded the Singularity test viewer, which appears to have signed me in and allowed me to fix my avatar and delete the house, but I can't move more than a few feet, nor can I fly. Possibly useful because it enables you to get in. This is a premium membership? I'm waiting for someone who is more computer savvy than I to help out here. God forbid SL should step in and help.
