I was having troubles with Viewer 2 today and decided to install 1.23 again just so I could get in some RP, but I can't logon to it. It gives me a window saying, "Unable to connect to Second Life. DNS could not resolve the host name." Is this viewer not compatible anymore?

Like, for instance, if you go to the Environment Settings, you can go to the Editor and move the bar to different times. But, how can I make this permanent, so that it will be dark when it's night time and light when it's day, morning when it's morning, etc.? I just think it would be more realistic, especially since I mainly RP.
