ACDS installation - code unit 99

Hi! On the CONSOLE ROOT/SERVICES, i got the following alert message, after having installed ACDS (using the Loopback Network Adapter option): “Trigger 99 in Codeunit 1 does not exist. This trigger must be executed to establish connection to the Message Bus.” Can anybody why i got that message? Thanks. Arr

…sorry, i missed the “List of typical problems” at the end the installation guide. [Oops!]
