supernatural season 4 and 3 down :(

i was watching yesterday and watched 2 of the 4 th season today i came from school and wanted to watch more but i just cant because season is down by that i press and there where yesterday was video today is just a black box

Yeah, I've been trying to watch season 3, Dream a little Dream of Me, and Mystery Spot, but all I get is a white box. It was working fine until that epsiode, so I would wager it's the links and not my computer.
I truly appreciate being able to come here and watch Supernatural, as DVD prices are still too high to buy. Thank you.
Sincerely,
Wolf.

I tried to watch season 4, but it doesn´t work!
