Hi, I'm familiar with the expand button and that was the first place I looked. I suspected that it would be in the Tuturial/Data Data installer. So, I tried re-running that stand-alone, but didn't even get a prompt for where it might install, it just ran off and did its thing. But, still no Audio Lib.
I only commented because I had the Audio Lib from SX1_Studio before. I had to re-install X1 to get it back. I don't use the Loops or One Shots much, but saw some being referenced in tutorials so checked that I did have them, and found I didn't. They always used to come with my Studio's (now Pro) installs.
By the way, I also discovered some of my plugin's seemed to get overwritten (Rapture/DimPro/Z3ta1/2) and had to re-install them (and their update chains) and the extra banks for each. Also, I had to re-discover that 'some' of these programs/VSTis need to be running as Admin before the the installer accepts the new reg (some don't). At least, I had already sorted out the SN/reg issues with the old store before this exercise and had them handy. Still, digging up old extra patch banks, etc was a PITA (for instance the DSF Proteus pack, which also does a blind install overlooking where I actually installed DimPro and its arcane patch dir methods.) Particularly, since Program Data is now a hidden dir. Just saying, and confirming the other comment above.
