imacro programing for the chat -- 2

it is not a big project . i used to have an imacro code to post individual chat message to each user in the chat page. it was working really good and i was firefox explorer . but when firefox upgraded the version of the explorer it is not working anymore. i just need someone to just retune the imacro and make it work with the later version of firefox explorer. no additional programming required just fix the current one. I AM LOOKING WHO IS EXPERIENCED IN IMACROS PROGRAMMING. retuning the program should not take more than 30 minutes
