Hi!
Sometimes i can't get some of the lines of a conversation. The person, who i chat with sees, that he sent the message (it appears on his chat screen), but i never get it at all. It's really annoying, because it leads to big misunderstandings and stuff. Please, if anybody can, help me! I have windows xp, wlm 8.1 and the latest plus.

p.s.: Sorry if this question is already answered, but i haven't seen it.

Thanks!
