Can you open ISOLB's in E3d or only individual ISOTM's

In E3D Draw 2.1.0.31 the button to open a ISOLB is greyed out but I can open the individual ISOTM's?  Can we not open the whole library with the backing sheet like we used to?  I'm in as a free user so rights shouldn't be a problem.  Same issue with SYLB's, can only open and view the individual SYTM's.
