Sounds like you're experiencing the DCC Pending error message - there is some help with it in
this thread. You may also want to use the Search feature - expand to 'All Forums' and 'All Posts' for best results, there have been a lot of threads about this issue in the past.
A couple of FYIs, firstly, it's not necessary to type your title in CAPS to get attention to yourself, it's considered shouting on IRC and therefore, rude. Also note that if you are mass file trading, this is not what mIRC is for - IRC means Internet Relay CHAT. Downloading things such as mp3s/movies/software/etc is illegal.
