Marios, I've setup the database and ran scripts in the order they appear in supplementary material, but receiving the following error when triggered the job "dba - updStats - ServiceBroker"....

Executed as user: xxxxx. Invalid object name '//UTILITY/UpdStats/InitiatorService'. [SQLSTATE 42S02] (Error 208) Transaction count after EXECUTE indicates a mismatching number of BEGIN and COMMIT statements. Previous count = 0, current count = 1. [SQLSTATE 25000] (Error 266). The step failed.

Would you be able to assist me with this situation, please...!!
