PDF Creator 1.2.3 print queue disappears

We have an instance where the PDF Creator print queue disappears from a users available printers.

This is affecting users on a thin client connected to a terminal server. Our terminal servers all run on Windows Server 2008 R2 Enterprise (service pack 1) and this happens randomly on any one of our 14 terminal servers.

The profile isn’t cached on the server when the user logs off and we have recreated his entire user profile but the problem keeps reoccurring.

Other than installing the latest version of PDF creator is there anything that can be done?
