Illustrator workflow

I offi­cially don’t get it. Mind you I’m work­ing from a CMYK file at some bizarre res­o­lu­tion and it’s just not scal­ing prop­erly at all, so it’s prob­a­bly not entirely my fault… the usual print-web mind­set prob­lem methinks. Only this is extra frus­trat­ing coz it’s due by this evening and I’ve got a Shake­speare scene to work­shop this evening also… so I’ve basi­cally got 3 hours left to build an entire web­site. Crap.
