I've installed iLok versions of all my VI libraries, they all show up fine when loading existing projects from before the conversion, except for some patches from "Orchestral Strings".
In particular these patches are missing:
51 VI-14B_perf-legato
01 VI-14B_staccato_long
41 VI-14B_pizz
51 VI-6B_perf-legato
01 VI-6B_staccato_long
41 VI-6B_pizz
32 VI-6B_trem_sus-fA_auto
(See attached screenshot)
I opened Directory Manager and rescanned the folders, but that didn't solve it.
