hi all i was wondering if any kind person could help me on a probleme

i got the online stuff and i installed my online i had the brick ps2 orginally (and i still got it turns on but doesn't read) now i have ps2 slimline got it from christmas so'z anyways i try o get online but every time i get through the second loading bar it gets to 3 on the 3rd and imedietly goes to error D900 and i got the connection i even checked the monster hunter site and it says that site does not exist.. soz what gives?
any ideas?
thanks in advance and more glory to those hunters that still play even if they don't.

well it seems that as of jan 1 08 they shut down mh online.i think it was to make way for mh2 online,so i would stop wating time trying to get on.fell free to ask me any questions on any mh game.happy hunting.
