Ok, I tried login second life homepage with Internet Explore, navigate a little, to get the certificate. Also, re-installed the viewer Second Life 2.5.1 (222408) Mar 1 2011 17:32:10 (Second Life Release). The problem still the same. I can't view any profile. I get a pink window with the name "about:blank" on the top and written in the page "SSL Handshake failed". Please, I need some help. I didn't see any other suggestion to fix this. I am using a PC with Windows Vista and Internet Explorer.
