I already logged in to open the client, after that i can't log in anyway! [ERROR] Uncaught exception! No idea whats wrong with it..

So i've just opened the bot, log in and my client opens, there's just a grey screen, saying im logged off in the bottom left corner and i can't seem to do anything, i've re-downloaded newest client and updated java, no idea what to do. love it if someone could help me, thanks in advance
