You need to listen carefully, this can happen if you have altered skill codes, or anything related to AGBOT. Please read this and do what I say.
This can also be caused by missing files.
I want you to uninstall AGBOT, and extract a brand new copy to your desktop, don't try to open yet.
Don't modify anything, yet.
Get AGBOT from here:
Install this:
And Reboot.
Install this:
And Reboot.
Install this:
Reboot.
Rebooting isn't really necessary, but do it anyway.
The reason I used SendSpace was just for convenience, and one of these installers isn't available anymore, please don't be afraid, I have not tampered with these, they came straight from Rev6 a few months ago.
