same here tooyeah, same problem here, an update was done this morning.
we are currently experiencing server issues and we are working on the situation.
I did not have problems until I updated my DB. Now for some reason the bot sent me back to authentication at 3 am last night. I woke up this morning, hit login and it didn't do the normal things, but start button was no longer greyed out. So I hit the start button and the bot is running WITH the authentication box popped up for me to login. I guess at least its working..
