It sounds like you're using some kind of file sharing script. Your best bet with any script is to ask the people who made it for help or ask on their forum/channel. If a channel requires a specific script, that channel should also be able to help you. If you want to start from scratch, you can always uninstall mIRC and reinstall whatever version you were using and then install the script (assuming the script doesn't work in 6.35... and in that case, it probably isn't a very good script).
