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. Your old versions of Dim Pro and Rapture will work with X3, at least they did for me.

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

Thanks!
