The DCC Pending error message is not directly an mIRC issue, it's related to Fserves. See
this sticky thread if you haven't already.
It's a good idea to have a quick glance at the sticky threads at the top of the forums as they are there to answer questions which are regularly asked by people.
You might also want to use the Forum's
Search feature and use "DCC pending" as the search term. Expand to 'All Forums' and 'All Posts' for best results.
Always keep in mind mIRC is mainly a text chat program and downloading off of fservers (and possibly mass file trading) is not only misusing mIRC but also risky.
Happy chattin'!
