I don't get it... what do Primedice chat or Chrome or Firefox have to do with it ?

You use English right, you don't use another language? If not maybe follow the advice of the person who was having a problem with the bot updating their balance and fixed it.

I removed the error messages because they were annoying (it just tries again instead of showing a messagebox) but I can give you a 'debug' version that has error messages so we could tell whats going wrong.
