have a friend we chat through IM's all of a sudden we cant communicate not in private IM's and not in open chat but we can in a group IM we are friends on eachothers friends list but for some reason we just cant communicate together unless its in a group chat i can stand in front of her and type in local and she dosent see it but if we are in a group chat she can answer me we both have since done a clean reinstall and still the same problem it dosent effect anyone else on our friends list just us
