I am about to do a new install of X3 on a new laptop. Do I have to download all of the above again or are they the same files as in X2?
Thanks for any input

There are no differences in Loops and One Shots or DimPro. No need to d/l them. There is no change to Rapture but it is part of the main SONAR installer. If you do not want to install it again, when installing SONAR run the advanced install option. Installing Rapture again will not hurt anything through.
