hey this is my first thread...and i need some help!

i logged off online play on resistance just like any other day and i tried to get back on. everything was fine. I was signed in my playstation network accepted both legality things. and then when it tried to load my buddy list thing, it gave me a black screen, saying nothing but just giving me the option to go back... has anyone had this problem? what do i do?
