You are trying to run an Accessory (such as the Slide Show) that requires an agent home directory when you run it from PC Access. However, the current agent's home directory is missing. Normally PC Access creates each agent's directory when you add that agent to the Agent Setup window. If you later remove that agent's directory from your hard disk, without also deleting that agent from your Agent List, you get this error when PC Access needs to use that directory again.
