It's been for days. I can't log in to SL. After more than 3 mins loading world, it logs me out ... This is my main avi, it's weird, itit's about firewall or viewer something, it shouldn't be because i log in with another avi, it can. This one just can't. Please help me. Below is picture shows what i get after loading the world in 3 mins. I used another avi to ask the estate manager of my land and she said my region is fine. So what's the problem? Please help... http://imageshack.us/photo/my-images/94/screenshot20120228at309.png/
