I have Trilian's library already installed on a SSD. I did a clean OS install on a new SSD. I don't want to rewrite Trilian on my samples SSD. I installed the software on the new OS drive, pointing to STEAM folder. I updated it. I authorized, scanned VST in Sonar Platinum. Trilian loads. No sounds will load and the module says it needs to be updated. I did that 2x, but it doesn't update, and says it's missing a synthbass sound. Trilian worked perfectly on the old OS drive. What's my next move?
 

I'd say contact Spectrasonics but they're likely all at NAMM

Did you say you already created an "alias" (shortcut) pointing to the STEAM folder?
