SinBot2.4 Does not skip maps

Using Pie's Binds or any other bind setup?

I've tried at least 3 different keys, and when I press them manually they all work.

See, had you searched through the original thread then you would have seen my answer tot the tooltip issue which I won't repeat because I couldn't be fucked bothering with it at the moment since I'm doing a complete system reset, and don't really have the time, or patience to.
On the other issue, you say that other keys work, but not the original one, which tells me that you didn't read the readme, and have something else bound to those keys, or need to do a bind clear first.

All keys work if I manually press them. None of them work through the bot.

Ahh, well, in that case, then it sounds like the download's either corrupted, or your hard drive may be. Try copying the bot into another folder, and running it, and see if it works, if it doesn't, try re-downloading it, and deleting the other two copies, and put the third somewhere else.
