Not sure what happened, but with 4.6, BHQ 'finally' showed up!
I don't know if this is just the licenses appeared or what. I wondered where it was for a while now. Also includes the apparatus.
So OF COURSE I checked to see if the BHQ Libronix resources would download and be recognized after synchronizing. Works!
Anyway check for BHQ if you previously bought the SESB. Maybe you're like me.
