[Answered] X3 - Are Dimension Pro 1.5, Loops and Shots, and Rapture 1.22 same as with X2?

I am downloading X3 as we speak, and have 2 questions:
 
1) Are the following files the same as the ones with X2?
03_Loops_And_One_Shots.part1.exe
03_Loops_And_One_Shots.part2.exe
03_Loops_And_One_Shots.part3.exe
04_Dimension_Pro_1_5_Setup.exe

2) After I placed my X3 order, I was given different serial numbers for Dimension Pro and Rapture 1.22.  Does this mean my X2 versions of Dimension Pro and Rapture will *not* work with X3, unless I somehow re-register them with the new serial numbers?  Or can I continue to use my old serial numbers as long as I don't install the X3 copy of Dimension Pro (and elect not to re-install Rapture 1.22)?
 
Thanks!

They are the same. No need to re-download or install.
