dont know why humour isnt appreciated... nothing else to do while downloading.... It isn't that humour isn't appreciated, it's that he specifically said what he's doing & why it's just wasting his time. What part of that did you miss? I agree with him. He wants to get this done, and keeps checking in for what turns out to be nothing more than 'smart ass answers' that are doing him absolutely no good whatsoever. And you have nothing else to do while downloading? Really? Wow!!

This list is detailed here for your verison of X2:

It would great to get a definitive answer to whether Loops and One Shots is necessary. I tried to install them and got a message about a corrupt file, so I am downloading the three files again. It would be nice to be able to run X2 and know it isn't going to crash. Anyone have any issues with the .exe's?

i dont think they are necessary unless you plan on using them. for X1 i only downloaded pts 1 and 2 and i was fine. im pretty sure the loops and Oneshots and additional content are optional patches and sounds and things of that nature, for Dim Pro, Rapture, and drag and drop.. i'd be surprised if any of that stuff is required for X2's core features.

Isn't a lot of it the reorganized Beatscape library.
