Any idea what's causing the App Store search to generate this error? No match found for app '2971/Black Opal Systems/Word Document Generation for Mendix' The module is definitely still there. It's mine and I can access it via 'My App Store'... but it seems nobody else can.
I was actually trying to access this module last week and received the same error. I just assumed it wasn't in the app store anymore. Did you file a ticket?
