XDCC catcher is a popular script to use mIRC for downloading files, mostly illegal ones. A lot of networks have it banned.
There's nothing *we* can do here, as mIRC is just an IRC client and has nothing to do with the running of IRC servers/networks. You'll need to use the above linked contact page.
Regards,
Actualy no... XDCC Catcher isn't a mIRC script. It is actualy like Bottler. It is coded in c++ or something like that and you don't need to have mIRC in order to connect to networks.
The reason, or at least on of the reason this application is being banned from irc network is because it creates a lot of connections to the server and floot channels and bots/users
