recenty when my mate tries to send me a song through msn it says "this file has been blocked because it is potentially unsafe"?
but i can send my mates files no problem at all.?

it used to work and ive changed nothing on my computer apart from downloading an update for msn(7).

anyone know what the problem is here or am i not the only person whos had this? or is it simply msn being a complet t*at yet agian!!
