First off I will start with my computer's Specs. Windows 7 64bit 4 GB DDR2 6400 Ram 2.0GHZ Intel DualCore Processor Nivida Geforce 7 Go 256MB dedicated video Ok so I already have run SecondLife on this computer before and just the other day it stoped working. The viewer freezes up at "Initializing VFS" and all I get is an empty box. It does not even show the login screen. Now I have googled this problem all night and the only solution I am able to find is about manualy clearing the cash and uninstalling and reinstalling. I have done ALL of this and nothing is working. Mind you that I am a Computer Tech and I still can not figure out this issue. All of my Drivers are also updated, that was one of the first things I checked. I also updated Java, Flash Player and Quicktime as well. I used to have this problem before because I did not have Microsoft C++ 2005, 2008, and 2010 installed, and also all of the Net Framworks, but this is all up to date and still nothing is working. If anyone has any other solutions please let me know. Thank You.
