[Plugin: Broadcast MU] Help needed!

I am having a lot of trouble with the Broadcast MU plugin which I just don’t know how to fix because I can’t understand what is going on, I have spent lots of time and gotten no where, I would really appreciate some assistance from the community to get the plugin working more reliably as currently I just don’t have the time to resolve all the problems people keep sending me but I want this to be a plugin for the community and not just for my university which is where the plugin was originally written for and intended to be use by, and it works fine for them so thats where I am getting stuck is I can’t reproduce the problems and I don’t understand why it doesn’t work either.
