I"m having issues logging in. It tells me my clock isn't set up right. Or to check my firewall settings. Nothing was changed. BUT if I keep trying to log in, it will allow me. But then, if I try to teleport, it crashes. Or if I make it, voice never loads again. Or sometimes half my clothes/hair is missing and Secondlife won't allow me to put them back on. I've checked my firewall, my clock setting. I've even reset my modem (which everything else is working fine that runs off the internet). Please help!!!??
