I`m trying to open the SL viewer but it crashes before the opening page appears. I tried a clean install, unistalled and reintalled multiple times and it didn`t work. Tried different viewers too and nothing. Checked my firewall, restored my system, checked my RAM, cleaned all the residual files and nothing works. Can anyone help me with that? I haven`t entered SL in a while and was looking forward to it. Thanks!
