Even on the vault it is breaking, unless their is a part 2 to download that I'm unaware of, or just that to run 2.4 you have to have 2.0 or something already in the folders. If that is the case, then I'm just doing it wrong (highly likely) and will have to download the last few versions of CEP too. New computer, old one went bye bye.
EDIT: Bah, I think I'm going stupid in my old age. If I'm understanding this right, 2.4 is an UPDATE of 2.3, the 2.3 DL has all the essential stuff, 2.4 just modifies those. Am I correct? Hope so, since I'm going back and downloading 2.3 right now.
