Cydia not working?

[starkall]

I'm on 4.3.3 and cydia won't refresh or let me DL stuff. It keeps saying like POISX error or something like that?

Which repository does the POISX error occur? A screenshot will help?

[starkall]

Just when cydia first loads it comes up with this error and won't let me DL anything

[Mes]

Did you let Cydia finish? This error will eventually time-out after a few minutes and sometimes go to a black screen with more details.

Screen shot where the black screen error(s) are displayed please?
