I've been researching and trying everything to get it to work. Let me stress that it does not freeze, it simply closes. I've performed a clean reinstallment, checked over the requirements, checked my drivers and updated etc, checked for programs that may cause it not to work such as teamviewer... Nothing has worked. Edit: I do use windows 7, I have hidden files showing, this is my FIRST time trying to set up and log in to second life and I have tried the first suggestion below.
