I just recently got Stealthbot and for a couple days I was getting those exact same messages and couldn't for the life of me figure out why. I went on the homepage and asked people there, and I ended up figuring out what I needed to do. I think I can fix your bot in like 3 seconds.
1. Open your bot.
2. Open the Settings menu and go to the "Edit Files..." section.
3. Select "Config File". It should open with Notepad.
4. The first line in your Config file will say "[POSITION]". Change it so that it says "[MAIN]".
5. Under that line, insert a new line (don't replace anything this time) that says "STARVerByte=CD".
6. Under that, insert a line (still not replacing anything) that says "SEXPVerByte=CD".
So now the top four lines of your Config File should look like this:
[MAIN]
STARVerByte=CD
SEXPVerByte=CD
LastSettingsPanel=0
Once you've done this, save and close the Config File, and then try to connect again. Hope this helps.
