YouTube Like bot (HELP)

Hello, i got a few accounts but for some reason when i use a bot to like the video, it gives me a error 403, the accounts are working and i could like my videos, i was thinking of creating a imacro in firefox but i don't know how to create a working macro. Always getting error, can someone create one please?

What kind of Bot? Also you need Flash Player active to like a video.

What bot are you using? Youtube always chang their system. So bot need update.

Error 403 would hint at either the account or video/channel being disabled but it's used for other errors as well, you can catch me on skype at nate.yourmoneybutton if you need to discuss further or try to find a solution.
