Its saying that second life cannot be accessed from this computer...I dont know why its saying that because I was just logged in secondlife yesterday and today I just can't log in for no reason at all I need help..it isn't because i'm banned or because of my IP address, I've already checked into that with secondlife I just need help logging in...and recently I had to buy my account back and I had two other alts that I didn't state to open when i bought my main acccount back..could that be the issue of my login failure ?
