I used to be able to connect to SL just fine from my school, and looking around, it look like some others are not having any problems, but i am. I have reset my computer internet connection, made sure i wasn't running any other programs, but its still not work, and it gives me, a "unable to connect to internet message" So whats going on? ohh and grid status is fine, just at school cant connect.
