The few times I get this message, actually just a moment two ago, I simply close the bot and start it again.
I typically hear a noise as if there is a prompt but it closes (I imagine I could look in the log, but this fixes the issue for me).
Odd. I thought I had redownloaded it. I thought I had the latest version. I have been getting it from the website. I have redownloaded it several times.
Well I don't know how to fix that... or even what that means... Guess I will try and get a friend to help me. I do know what a Zip file is... but how to fix it... *shrug*
