The problem is in the option file.
In the INCREMENT line of the license, find all "USER_BASED" products.
Change the word INCREMENT to "INCLUDE", copy / paste the product purchased.
Do this ONLY for the lines with USER_BASED in them. Not for the sub level features.
Example Option file:
GROUPCASEINSENSITIVE ON
GROUP ps_on_tc iamfritz
GROUP plantsim iam2tall
INCLUDE CAR_PROCESS_SIMULATE GROUP ps_on_tc
INCLUDE FEA_PLANTSIM_GANTT2 GROUP plantsim
INCLUDE FEA_PLANTSIM_VSM_LIBRARY GROUP plantsim
Notice GROUP "plantsim" will be used on two different USER_BASED products.
FEA_PLANTSIM_GANTT2 & FEA_PLANTSIM_VSM_LIBRARY
