there can be a number of reasons in which u may not hav been able to login, u may not be sharing anything, the hub could be restarting, u didnt hav any slots available etc.
reasons for u nt being able to downlaod anything can be that u were not in active mode, the person u wer downloading from had no more slots, if this happens jus ask the user and they will giv u a slot to download.
