We've freshly migrated our Groupwise 2014 to 18.0.2 and I've installed Groupwise client 18.0.2 version 131493 (French version) and I'm experiencing some issues displaying emails, only first email of a conversation is displayed and all others are showing only an error message which is : Critical Security Component wasn't loaded by Groupwise (I'm translating because in French it is "Un composant de sécurité critique n'a pas pu être chargé par GroupWise".
I don't know what I've missed or how to solve, thanks for help!
