the bot will not start with the DK

As mentioned in the title, my bot does not start when using my DK. I start the bot, do I login and then tells me "attached to WoW with ID 4300" and it stops there. I'm not allows choosing the CC, it kind of bot, nothing.
If I logout and login another pg, without closing WoW, but only restarting the bot, then starts easily and it works.

* to which may be due?

 

Delete your settings folder please.

 

now works perfectly, thanks
