Cydia doesnt load! 2.0

[plastictrees]

I just bought an iPhone that was unlocked and has Cydia on it. Everytime i try to open up cydia, it just comes up and then flashes back to the home screen. Is it supposed to be doing that?

repwn it.. or try to ssh chmod cydia to 775 755 or watever

Do i need to downgrade it or anything? or can i repwn it straight from 2.0

I have the same problem with 2.0.1, I've re-pwned twice and it still won't load.
