AdiIRC

I'm using AdiIRC 1.8.3 with my fellows. DCC send starts normally: DCC window opens and reciever gets popup about incoming send. I accept it, but then nothing happens. This happens everytime. No matter who is sending or recieving.

I also tried to send file to my laptop. Same result. I'm using Comodo Internet Security on both machines and I checked that it don't limit AdiIRC's traffis, so configures are right. I also checked packet traffic with Wireshark. It seems, that AdiIRC sends send-Request and reciever answers with Response, but then nothing happens. Reciever actually sends TCP-responses after that, but sender never reacts on those.

I'm running Vista Home Premium on laptop and XP Professional on PC.
