hi there im trying to rejoin secondlife after several years! im using windows 7 64 bit ultimate edition with nvidia geforce 8400 GS. Everytime the viewer gets to the message "initialising vfs" it crashes and i get a windows message saying the program has stopped working properly. i have reinstalled it 3 times and it still crashes at this point... any ideas? i have noticed my C drive is a little full.. could this be affecting it? cheers ------------------------- thanks solution below worked a dream! (couldnt find a reply button - either there isnt one or its way past my bedtime ;)
